This color state is easy to identify, and the powder has its unique properties when operated and used. Its texture is fine, easy to disperse, and it exhibits different characteristics from bulk or granular substances in mixing, dissolution, etc.
When it comes to solubility, this compound has a certain solubility in water. Water can interact with it, and intermolecular forces make some compounds dissolve to form a uniform solution. However, the degree of solubility is not infinite, and it is determined by factors such as temperature and concentration. Increasing the temperature usually increases the amount of solubility in water. Because of the increase in temperature, the thermal motion of molecules intensifies, which is conducive to the interpolation and mixing of compound molecules and water molecules. In organic solvents, such as ethanol and acetone, there are also different degrees of solubility. In ethanol, due to the mutual adaptation of the polarity of ethanol and the polarity of compound molecules, it can be better dissolved, which is the basis for its application in organic synthesis, extraction and other processes.
Melting point is also an important physical property. It has a specific melting point. When heated to this temperature, the compound changes from a solid state to a liquid state. The accurate determination of this melting point temperature can provide a key basis for the identification of the compound, and during the purification process, its purity can be judged by the melting point. If the compound is pure, the melting point range is relatively narrow; if it contains impurities, the melting point is reduced and the melting range is widened.
Furthermore, the density cannot be ignored. Its density determines the settlement and floating of the compound in different media, and affects the distribution and stratification of each component in the liquid mixture system. This property has important applications in chemical production and separation processes. According to the density difference, the separation operation can be carried out by sedimentation, centrifugation and other methods.
In summary, the physical properties of 1 - [Ethyl (3 - Methylphenyl) Amino] Propane - 1 - Sulfonic Acid, such as color state, solubility, melting point, density, etc., are interrelated and together determine their behavior and application in various chemical and industrial processes.

1 - [Ethyl (3 - Methylphenyl) Amino] Propane - 1 - Sulfonic Acid, this is a sulfonic acid compound. When storing, many matters need to be paid attention to.
First environmental conditions. This compound should be stored in a cool place, because high temperature can easily cause its properties to change or cause chemical reactions. If the temperature is too high, the structure or instability of sulfonic acid groups will affect its chemical properties and quality. And it should be kept dry. Moisture can easily make the substance absorb moisture, or cause it to dissolve or agglomerate, which will affect the use. Therefore, the warehouse needs to be well ventilated to disperse moisture and maintain a dry environment.
Times and packaging selection. Be sure to use well-sealed packaging materials to prevent air and moisture from invading. Glass bottles, plastic bottles and other packaging can be used, but it is necessary to ensure that the material does not react with the compound. For example, some plastic materials or undesirable phenomena such as swelling with sulfonic acid, so the selection of packaging materials is crucial.
Furthermore, to avoid mixing with incompatible substances. This compound should be kept away from oxidants, strong bases, etc. Oxidants meet with the substance containing amino groups and sulfonic acid groups, or cause oxidation reactions, destroying the molecular structure; strong bases may neutralize with sulfonic acid groups and cause their failure.
In addition, the storage area should be clearly marked to warn against unrelated personnel. Managers need to be familiar with the properties and storage requirements of the substance, follow relevant safety procedures, regularly check the storage status, check whether the packaging is damaged, whether the substance has deteriorated, etc., to ensure safe storage. In this way, 1 - [Ethyl (3 - Methylphenyl) Amino] Propane - 1 - Sulfonic Acid must be properly stored to stabilize its properties for subsequent use.

To obtain 1 - [Ethyl (3 - Methylphenyl) Amino] Propane - 1 - Sulfonic Acid, the following ancient method can be used.
First, take 3 - methylaniline and place it in a clean reaction vessel. Dissolve it in an appropriate amount of solvent such as ethanol to make a uniform solution. In this solution, slowly add bromoethane, and at the same time, gently stir to assist the reaction. It is necessary to pay attention to control the reaction temperature and maintain it in an appropriate range, about 50 to 60 degrees Celsius. This is because the temperature is too high or too low, which may affect the rate and yield of the reaction. This reaction is a nucleophilic substitution reaction, which lasts about 3 to 4 hours to obtain N-ethyl-3-methylaniline.
Then, the obtained N-ethyl-3-methylaniline is moved to another reaction instrument. Add sodium acrylate and an appropriate amount of catalyst, such as potassium carbonate. Use an organic solvent such as N, N-dimethylformamide as the reaction medium and mix it evenly. Then raise the temperature of the reaction system to 80 to 90 degrees Celsius and continue to stir for about 6 to 8 hours. This step is an addition reaction in which N-ethyl-3-methylaniline is added to sodium propenesulfonate to obtain 1 - [Ethyl (3-Methylphenyl) Amino] Propane-1 - Sulfonic Acid.
After the reaction is completed, the reaction mixture is cooled to room temperature. Then, the separation and purification are carried out by a suitable method. The organic solvent can be removed by vacuum distillation, then the residue is dissolved in water, and then the impurities are extracted with an organic solvent such as ethyl acetate. The aqueous phase is taken, and its pH value is adjusted to acidity, so that the product can be precipitated in solid form. Finally, 1 - [Ethyl (3 - Methylphenyl) Amino] Propane - 1 - Sulfonic Acid can be obtained by filtration, washing and drying.

"1 - [Ethyl (3 - Methylphenyl) Amino] Propane - 1 - Sulfonic Acid" is 1 - [Ethyl (3 - Methylphenyl) amino] propane - 1 - sulfonic acid. The market price range of this compound varies due to a variety of factors.
First, the purity of the product has a great impact on the price. If the purity is extremely high, it is close to 99% or more of the purity of the scientific research grade. Because the preparation process requires more delicate and complex processes, it is difficult to remove impurities, and the cost is high. The price per gram may reach hundreds of yuan. For example, in some high-end scientific research experiments, the purity requirements are strict, and the price is naturally high.
Second, the purchase volume is also a key factor. If you buy a small amount, such as a few grams in a laboratory, the supplier will consider operating costs and profits, and the unit price will be higher. However, if you buy a large amount, such as industrial production needs, a purchase of several kilograms or even more, suppliers may reduce costs due to scale effects and give certain discounts, and the unit price may be reduced to tens of yuan per gram.
Third, the market supply and demand relationship also affects the price. If there is a surge in demand for the compound in many industries at a certain time, and the supply is relatively insufficient, the price will rise; conversely, if the market demand is weak and the supply is sufficient, the price may fall.
Fourth, different suppliers have different pricing strategies. Some suppliers focus on high quality and the high-end market, and their prices are relatively high; while some suppliers win by volume and attract customers by lowering prices.
Overall, the market price range of this compound is roughly tens to hundreds of yuan per gram. The specific price needs to be determined in detail according to the actual purchase of purity, quantity, market supply and demand, and suppliers.
