(4- { (E) -Amino [ (diaminomethylene) amino] methylene} amino) benzenesulfonic acid, this is a chemical substance. To know its Quality Standard, although the specific material standard is not detailed in past books, some key points can be deduced by referring to the general quality standard of chemicals.
In terms of purity, it should have high purity, and the impurity content should be extremely low. Due to impurities or affecting its chemical properties and reaction effect, in a specific chemical reaction, there are too many impurities or reaction deviations. For example, in the preparation of pharmaceutical intermediates, impurities or interfere with the reaction path, making the product impure and affecting the efficacy. Therefore, the purity or requirement is 98% or more to ensure that the main component is dominant.
Appearance morphology, usually should be white or off-white crystalline powder. If the color is abnormal or the morphology does not match, or suggests that there are impurities mixed or the product deteriorates. Such as yellow color, or due to oxidation and other factors to change the chemical structure of the product.
Solubility is also an important indicator. In a specific solvent, it should have a specific solubility. If it is in water, it should be dissolved in a certain proportion. If the solubility is poor, it may affect its application in an aqueous solution system. For example, when used in some water-based coating additives, poor solubility will cause uneven dispersion and affect the performance of the coating.
Moisture content needs to be strictly controlled. Excessive moisture or cause moisture decomposition, which affects the stability of the substance and chemical reactivity. Generally, the moisture content may be limited to less than 1% to maintain its chemical stability.
Residues of heavy metals and harmful substances must comply with relevant regulations and safety standards. If the substance is used in food, medicine and other fields, heavy metal residues exceeding the standard will endanger human health, such as lead, mercury and other heavy metal residues, long-term exposure or accumulation in the body, damage to human organs.
Although there is no exact book detailing its Quality Standards, the above key Quality Standards can be deduced according to the general nature of chemical substances and the requirements of application scenarios to ensure the quality and application effect of the substance.
