It is a rare good product.

The physical properties of m-hydroxybenzenesulfonic acid are as follows:
This substance is mostly solid under normal conditions, and it usually appears as a white to slightly yellow crystalline powder. The color is pure and the texture is uniform. This appearance is conducive to identification and preliminary discrimination.
Smell, m-hydroxybenzenesulfonic acid does not have a strong pungent smell, but only has a light and inconspicuous smell. In ordinary environments, its smell is difficult to cause significant impact on the surrounding air, and it will not cause discomfort due to the smell.
When it comes to solubility, m-hydroxybenzenesulfonic acid exhibits good solubility in water. When exposed to water, it can gradually disperse and integrate into the water body to form a uniform solution, just like ice and snow melting in a stream when warm. In ethanol, it also has a certain solubility, but the degree of solubility is slightly inferior to that of water.
Furthermore, the melting point of m-hydroxybenzenesulfonic acid is quite critical. After many researchers have investigated and determined, its melting point is within a specific range, which is an important basis for determining its purity and quality. The stability of the melting point symbolizes the regularity and uniformity of the internal structure of the substance.
Its density is also the main point of physical properties. Having a specific density value indicates that its mass per unit volume is constant. This characteristic plays an indispensable role in many practical application scenarios, such as material ratio and process control. The physical properties of m-hydroxybenzenesulfonic acid, from appearance, odor, solubility, melting point to density, each have their own unique characteristics, which are the basis for in-depth understanding and application of this substance.

The chemical properties of m-hydroxybenzaldehyde, also known as m-formaldehyde phenol, are relatively stable.
In m-hydroxybenzaldehyde, the hydroxyl group and the aldehyde group are in the interposition of the benzene ring. The benzene ring itself has a certain stability, and its large π bond structure makes it able to resist the attack of some common reagents. The hydroxyl group as the power supply can increase the electron cloud density of the benzene ring, and have a certain activation effect on the electrophilic substitution reaction on the benzene ring. However, due to its interposition with the aldehyde group, the space steric resistance and the comprehensive influence of electronic effects, the molecule is relatively stable under general conditions.
aldehyde group, as an important functional group of m-hydroxybenzaldehyde, has the typical properties of aldehyde. It can undergo an oxidation reaction. Under the action of mild oxidizing agents such as silver ammonia solution or new copper hydroxide suspension, it can be oxidized to carboxyl groups to form m-hydroxybenzoic acid. However, in the absence of such oxidizing agents, the aldehyde group is relatively stable. At the same time, the aldehyde group can also undergo a reduction reaction. Under the action of suitable reducing agents such as sodium borohydride, it can be reduced to alcohol hydroxyl groups to form m-hydroxybenzyl alcohol. However, if there is no reducing agent involved, the reduction reaction will not proceed spontaneously. The stability of
m-hydroxybenzaldehyde is also reflected in the fact that it does not undergo rapid chemical reactions with common substances such as water and air at room temperature and pressure. It has a certain solubility in organic solvents, and its chemical structure does not change during the dissolution process. However, under extreme conditions such as strong acid, strong base or high temperature, its stability will be affected, and reactions such as hydrolysis and rearrangement may occur.
In summary, under common conditions, the chemical properties of m-hydroxybenzaldehyde are relatively stable, but under specific chemical reagents or extreme conditions, corresponding chemical reactions will occur.

There are various methods for the production of m-hydroxybenzaldehyde. In the past, chemical synthesis was mostly used, but now there are also biological synthesis methods that have emerged.
First, in chemical synthesis, there are many people who use m-cresol as the starting material. The reaction of m-cresol through formylation can produce m-hydroxybenzaldehyde. In the process, m-cresol is first combined with appropriate reagents, such as phosphorus oxychloride and N, N-dimethylformamide, at suitable temperatures and conditions. In this reaction, phosphorus oxychloride reacts with N, N-dimethylformamide first to generate an active formylation reagent, and then undergoes electrophilic substitution with m-cresol. The formyl group then replaces the hydrogen atom on the m-cresol benzene ring to obtain the precursor of m-hydroxybenzaldehyde. After subsequent steps such as hydrolysis, the finished product is purified. In this way, attention should be paid to the control of the reaction temperature. If the temperature is too high or low, it can increase the side reaction and damage the yield.
Second, the method of biosynthesis has also attracted more and more attention. Using microorganisms or enzymes as catalysts, through specific metabolic pathways, the generation of m-hydroxybenzaldehyde can be realized. Such as some bacteria or fungi, in a suitable culture environment, can use specific substrates to convert them into m-hydroxybenzaldehyde through the catalysis of enzymes in the body. This biosynthetic method has the advantages of green environmental protection and mild reaction conditions. However, there are also difficulties in screening strains and complicated fermentation processes. It is necessary to carefully select high-efficiency strains and optimize fermentation conditions, such as temperature, pH value, substrate concentration, etc., to improve yield and purity.
Or there are other raw materials and pathways, but the above two are common methods. Chemical synthesis has a long history and mature technology, while biosynthesis is an emerging trend with great potential. Both of them are in the production of m-hydroxybenzaldehyde and each has its place to promote the development of this field.

When storing and transporting m-hydroxybenzenesulfonic acid, many matters need to be paid attention to.
When storing, the first priority is the environment. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources. Due to its nature or sensitivity to temperature and humidity, high temperature and humidity are easy to deteriorate, so the warehouse temperature should be properly controlled, and the humidity should also be maintained within an appropriate range. Furthermore, it should be stored separately from oxidants, acids, alkalis and other substances to avoid chemical reactions caused by mixed storage and potential safety hazards. At the same time, the storage area should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment, just in case.
When transporting, be sure to ensure that the packaging is complete. Packaging materials should be sturdy and durable, able to withstand bumps and collisions during transportation, and prevent leakage of m-hydroxybenzenesulfonic acid due to damage to the container. Transportation vehicles should also meet safety standards and have fire and explosion-proof facilities. During transportation, drivers and escorts should pay close attention to the condition of the goods to avoid prolonged exposure to the sun or high temperature environments. In addition, transportation route planning should also be careful to avoid densely populated areas and environmentally sensitive areas to prevent leakage from causing serious harm to the public and the environment. During loading and unloading, operators should load and unload lightly, and it is strictly forbidden to drop and drag to ensure operation norms and ensure the safety of personnel and the integrity of goods.
