3,5-Bis (hydroxymethyl) isoxazole-4-carboxylic acid is an organic compound. Its physical properties are as follows:
Under normal temperature and pressure, this substance is often in the state of white to light yellow crystalline powder, with a fine appearance and uniform texture, which is easy to observe and handle.
When it comes to solubility, it has a certain solubility in water, which is related to the polar groups contained in the molecular structure. Because of its polar parts such as hydroxymethyl and carboxyl groups in the molecule, it can attract water molecules through hydrogen bonds and other interactions, thereby partially dissolving in water. In common organic solvents, alcohols such as methanol and ethanol have considerable solubility, while in non-polar solvents such as n-hexane and benzene, the solubility is very small. This difference in solubility is of great significance in the separation, purification and choice of reaction medium of compounds. The melting point of
is also one of its key physical properties. After determination, the melting point of the substance is in a specific temperature range. The exact value of the melting point is its inherent property and is influenced by intermolecular forces. The strength of intermolecular hydrogen bonds, van der Waals forces, etc., determines the energy required to convert a solid state into a liquid state, that is, the melting point. Accurately knowing the melting point can be used to judge the purity of the compound. If the purity is high, the melting point range is narrow and close to the theoretical value; if it contains impurities, the melting point is reduced and the melting range is widened.
In addition, the density of the compound is also an important physical parameter, and its density reflects the mass per unit volume of the substance. For applications in different systems, such as solution preparation, reaction system design, etc., density data can help to accurately calculate and control the dosage of each substance to ensure the accuracy and stability of the experiment or production process.

To prepare 3% 2C5-bis (hydroxymethyl) pyridinecarboxylate, the following method can be used.
First take an appropriate amount of 3,5-dimethylpyridine, place it in a reactor, add an appropriate amount of catalyst, such as a metal salt catalyst, at a specific temperature and pressure, introduce oxygen or air to carry out an oxidation reaction. This oxidation reaction aims to oxidize the methyl of 3,5-dimethylpyridine to carboxyl groups to obtain 3,5-pyridinedicarboxylic acid. During the reaction, close attention should be paid to changes in temperature and pressure to ensure the smooth progress of the reaction.
When 3,5-pyridinedicarboxylic acid is obtained, remove it and dissolve it in a suitable solvent, such as a polar organic solvent. After that, a formaldehyde solution is added, and a basic catalyst is added, and the hydroxymethylation reaction is carried out at temperature. The key to this step is to control the amount of formaldehyde, the reaction temperature and time, so that the carboxyl ortho-position of 3,5-pyridinedicarboxylic acid can be successfully introduced into hydroxymethyl groups to obtain 3% 2C5-bis (hydroxymethyl) pyridinecarboxylic acid.
Finally, 3% 2C5-bis (hydroxymethyl) pyridinecarboxylic acid is mixed with alcohols, such as methanol and ethanol, in a certain proportion, and an appropriate amount of acid catalyst, such as sulfuric acid, is added to carry out esterification reaction under the condition of heating and reflux. After the reaction is completed, the pure 3% 2C5-bis (hydroxymethyl) pyridinecarboxylate can be obtained through separation and purification steps, such as extraction, distillation, recrystallization, etc. The whole process requires fine operation and strict observation of reaction conditions to obtain the ideal product.

3,5-Bis (hydroxymethyl) isoxazole-4-formic acid. When storing and transporting this substance, many key points must be paid attention to.
Its nature or more active, in case of heat, open flame, oxidizer, etc., it may be dangerous. Therefore, when storing, it is advisable to choose a cool, dry and well-ventilated place, and be sure to keep away from fire, heat sources and strong oxidizers. The storage temperature also needs to be precisely controlled to prevent it from decomposing and deteriorating due to excessive temperature, which threatens safety.
When transporting, extra caution should also be taken. The packaging must be tightly packed to ensure that there is no risk of leakage under bumps, vibrations, etc. Due to its certain chemical activity, transportation vehicles need to be equipped with corresponding fire protection equipment and leakage emergency treatment equipment for emergencies.
During loading and unloading, operators should handle it with care to avoid package damage caused by brutal operation. At the same time, environmental conditions should be monitored at all times during transportation, such as temperature, humidity, etc. If there is any abnormality, immediate measures should be taken.
Furthermore, whether it is storage or transportation, relevant places and vehicles should be strictly marked, indicating their chemical characteristics and dangerous precautions, so that all relevant personnel can see at a glance and avoid accidents caused by ignorance. In this way, 3,5-bis (hydroxymethyl) isoxazole-4-carboxylic acid can be guaranteed to be safe in storage and transportation.

The price of various things in the city often changes over time and varies according to quality. Today, it is not easy to know the market price range of 3,5-bis (methoxymethyl) pyridinecarboxylate, and its price is subject to many factors.
The production of this product is related to the abundance of raw materials and the difficulty of craftsmanship. If the raw materials are abundant, easy to harvest, and simple to make, the production will be more, and the price will be easier; on the contrary, if the raw materials are rare and the craftsmanship is difficult, the production will be less and the price will be high.
Furthermore, the supply and demand of the market are also the main reasons. If there are many people who ask for it, but there are few people who supply it, the price will increase; if the supply exceeds the demand and the market is difficult to sell, the price will be depressed.
And its wide and narrow use also affects its price. If it is suitable for various industries and has many uses, people will compete for it, and the price will be high; if it is used in a limited way and only suitable for one or two places, the price will not increase significantly.
However, I have not yet obtained the exact number. Roughly speaking, the price may vary from tens of gold to hundreds of gold per catty depending on the quality. Made by Gaijiapin Seiko, the purity is high, the impurities are few, and the price should be the highest; while the crude one contains more impurities and the quality is inferior, the price is slightly lower. And the market conditions are ever-changing, and the price is also impermanent. To know the real-time price, you need to carefully investigate the market and ask the merchants before you can be sure.
