The physical properties of "6-hydroxyl-2-methyl-3-pyridyl" are as follows:
This is one of the structural expressions of organic compounds. From the perspective of physical properties, under normal circumstances, such compounds containing specific functional groups are mostly solids or viscous liquids. If the intermolecular forces are strong, such as the presence of more hydrogen bonds or the large van der Waals forces, the melting point and boiling point will be relatively high. For example, when the hydroxyl groups (-OH) in the molecule can form hydrogen bonds, the intermolecular interactions will be enhanced, and the boiling point may increase.
Its solubility is also related to the structure. Hydroxyl groups are hydrophilic groups and can form hydrogen bonds with water, so the substance may have a certain water solubility. However, the hydrophobic moiety of methyl (-CH
) and pyridyl groups will reduce their solubility in water. Overall, in polar solvents such as ethanol and acetone, its solubility may be better than that of non-polar solvents such as n-hexane.
In terms of chemical properties, hydroxyl groups have certain reactivity. It can participate in esterification reactions and form ester compounds with carboxylic acids under the action of catalysts. For example, when reacted with acetic acid, under the catalysis of concentrated sulfuric acid and heating conditions, the corresponding esters and water are formed. At the same time, the nitrogen atom of pyridyl groups has lone pairs of electrons and is alkaline, which can react with acids to form salts. Methyl groups are relatively stable, but under specific conditions, such as high temperature, light and the presence of suitable reagents, substitution reactions can also occur. The compounds of this structure are widely used in the field of organic synthesis, and are often used as intermediates in the preparation of various drugs, pesticides and functional materials.

"6-Hydroxy-2-methyl-3-pyridyl" This chemical substance has unique chemical properties. In its molecular structure, the hydroxyl group (-OH) imparts hydrophilicity and easily forms hydrogen bonds with water molecules, which affects the solubility of the substance, and the solubility is good in polar solvents. Methyl (-CH 🥰) is an alkyl group, which has a certain electron-giving effect, changes the distribution of molecular electron clouds, affects the reactivity, and increases the density of adjacent and para-potential electron clouds, making electrophilic substitution reactions more likely to occur at these locations. Pyridyl groups, as nitrogen-containing heterocycles, have lone pairs of electrons and are alkaline. They can react with acids to form salts, and also affect the electronic structure and reactivity of the entire molecule.
In a chemical reaction, "6-hydroxyl-2-methyl-3-pyridyl" can be esterified due to the presence of hydroxyl groups, and esters can be formed with carboxylic acids under the action of catalysts; hydroxyl groups are also easily oxidized, and formaldehyde, ketones or carboxylic acids are formed according to different conditions.

In short, this chemical substance exhibits rich chemical properties due to the synergistic effect of various groups, and has important application value in organic synthesis, medicinal chemistry and other fields.

The synthesis method of "6-hydroxy- 2-methyl-3-pyridyl", although not directly described in Tiangongkai, can be deduced from ancient chemical process ideas and similar synthesis ideas.
Ancient chemical processes rely on fire and water methods. To synthesize this substance, you can first look at its structure, "6-hydroxy- 2-methyl-3-pyridyl" contains hydroxyl groups, methyl groups and pyridine rings.
For fire methods, natural materials containing pyridine structures, such as certain plants or minerals, can be found by calcination. At an appropriate temperature, in a ceramic crucible, closed calcination. Under high temperature, the material components decompose, rearrange, or form a basic structure containing pyridine rings. If the material contains methyl groups, under certain conditions, it may retain the 2 positions of methyl-based pyridine rings. As for the 6-position hydroxyl group, or after calcination, the product can be leached in water, and the oxygen in the water may be able to combine with the 6-position pyridine ring to form hydroxyl groups. This process requires control of temperature, time and material ratio.
Water method is also possible. Select compounds containing pyridine and methyl precursors, dissolve in water, and add appropriate additives, such as certain metal salts. Metal ions may catalyze the reaction. In a kettle, heated in a warm water bath to keep the temperature stable. Compounds interact with each other in water to gradually build a pyridine ring, and at the same time introduce a methyl-based 2-position. Then through appropriate oxidation steps, such as air or weak oxidants, under specific pH conditions, the 6-position pyridine ring is oxidized to hydroxyl groups.
The synthesis process requires repeated attempts to adjust the temperature, time, material ratio and other conditions in order to obtain the best synthesis effect. Although there is no confirmation in "Tiangong Kaiwu", but according to the ancient chemical process wisdom, a feasible synthesis path may be explored.

"6-Hydroxy-2-methyl-3-furanylacetonitrile" is within the price range of the market, and it is difficult to determine. The price of such things often changes due to various reasons.
First, the source flow of the material quality has a lot to do with the coarseness. If the raw materials required for its preparation are obtained from a favorable place and refined, the price is high; on the contrary, if the raw materials are easily available and of affordable quality, the price should be cheaper.
Second, the craftsmanship is also the key. If the preparation method is exquisite, it can be produced efficiently, and the quality is high, although the cost or high, the quantity can also change the price. If the craftsmanship is simple and the production efficiency is low, the price will be affected by it.
Third, the state of supply and demand in the market affects its price. If the product is needed by everyone in the market, and the demand exceeds the supply, the price will rise; if the supply exceeds the demand, the merchant will sell the product or reduce the price to promote it.
Fourth, the restrictions of government decrees and laws also have an impact. If this product involves special control, its production and circulation are limited, and the cost may increase, and the price will also follow.
To sum up, in order to determine the exact price of "6-hydroxy- 2-methyl-3-furanoacetonitrile", the above things must be carefully considered in order to obtain a more accurate price range. However, only in this name, it is difficult to determine the geometry of its price.
