6-Methyl-3-pyridine sulfonic acid, this is an organic compound with unique physical properties. Its appearance is often white to off-white crystalline powder, which is quite stable in air and is not easily affected by common environmental factors and rapidly deteriorates.
When it comes to solubility, 6-methyl-3-pyridine sulfonic acid is easily soluble in water, which makes it easily dispersed and participated in many chemical reactions or solution systems involving the aqueous phase. After it is dissolved in water, it can form a uniform solution, providing a good medium environment for related reactions. In addition to water, it also has a certain solubility in some polar organic solvents, such as methanol, ethanol, etc. This solubility property broadens the range of choices in different reaction conditions and application scenarios, and can flexibly select the appropriate solvent system according to specific needs.
In terms of melting point, the substance has a relatively clear melting point range. Accurately determined melting point data is essential for identifying its purity and studying the phase change under specific temperature conditions. By measuring the melting point, it is possible to determine whether the compound is pure. If it contains impurities, the melting point will often be offset or the melting range will be widened.
The density of 6-methyl-3-pyridine sulfonic acid is also one of its important physical properties. The specific density value reflects the density of its molecules and the relationship between mass and volume. This property is crucial in processes such as the separation and mixing of substances, and in processes involving density-dependent calculations. For example, in liquid-liquid separation operations, its density characteristics help to determine the distribution of the substance in the mixed liquid, thus enabling efficient separation and purification.

6-Methyl-3-pyridine sulfonic acid has stable properties. In its structure, the pyridine ring has aromatic properties, which makes the molecule stable to a certain extent. The methyl group is attached to the pyridine ring, and the spatial resistance is small, which has limited effect on the structure and does not cause a significant increase in activity. Although the sulfonic acid group has a certain polarity and reactivity, it interacts with the pyridine ring, and the overall structure is not prone to drastic changes under common conditions.
At room temperature and pressure, if there is no special chemical reagent or extreme conditions, this compound can persist for a long time and change less. In case of common acid and base, due to the alkalinity of the pyridine ring and the acidity of the sulfonic acid group, there will be a certain acid-base reaction, but it will not be Only under severe conditions such as strong acids, strong bases or high temperatures, it will react significantly and cause structural changes.
Because of its heteroatoms such as sulfur and nitrogen, although in a stable state, in the case of strong oxidizing agents or reducing agents, it can react due to changes in the valence state of heteroatoms. However, in general environments, if there is no such strong active substance, 6-methyl-3-pyridine sulfonic acid can be stable, can be stored and used as usual, and its chemical properties will not change suddenly for no reason.

6-Methyl-3-pyridine sulfonic acid, the method of its preparation, although the ancient book "Tiangong Kaiwu" does not explicitly mention this substance, it can be deduced from the general principles of chemical industry.
First, 6-methyl pyridine is used as the starting material, which is the basic material. In an appropriate reactor, add an appropriate amount of concentrated sulfuric acid, sulfuric acid, which has strong oxidizing and sulfonation ability. Temperature control is in a specific domain, covering the temperature is related to the speed of the reaction and the purity of the product. At the beginning, the temperature gradually rises, and it should not be rushed to prevent side reactions from clumping. When it rises to a suitable temperature, or between hundreds of degrees, 6-methyl pyridine and sulfuric acid slowly phase.
During the reaction, stir well to allow the reactants to be fully touched. The sulfo group of sulfuric acid gradually combines with the specific check point of 6-methylpyridine, and over time, a crude product of 6-methyl-3-pyridine sulfonic acid is formed.
However, this crude product is still miscellaneous and needs to be purified by refining method. An appropriate amount of solvent, such as alcohol or water, can be used. According to its solubility, it has been dissolved, filtered and crystallized many times. First dissolve the crude product in a suitable solvent, heat it to help dissolve, then cool down and crystallize, during which impurities are left in the mother liquor, filtered off, and dried at low temperature to obtain pure 6-methyl-3-pyridine sulfonic acid. Although this method is not contained in the ancient recipe, the principles of chemical industry are inherited from ancient and modern times. According to modern science, this substance can be prepared.

The price of 6-methyl-3-pyridine sulfonic acid in the market often varies due to various reasons. Looking at the past "Tiangong Kaiwu", the price of materials depends on the place of production, season, supply and demand conditions, etc.
This 6-methyl-3-pyridine sulfonic acid, if the product is abundant, and the buyer is not available, its price may be inexpensive; if the origin is sparse and wide, and there are many people who need it, the price must rise.
In the past, the price of various materials can be inferred. If there is no big disturbance, the price of this acid may be between tens of yuan and hundreds of yuan per kilogram. However, the market situation changes like the situation, or the yield increases due to new technologies, and the price also decreases; or the price increases due to lack of raw materials and changes in regulations.
Therefore, in order to determine its accurate price, it is necessary to carefully examine the current market supply and demand, production conditions, and various market changes in order to obtain its accurate price range.
