22536-65-8 - Introduction
A Crystal, also known as a crystal, is an organic compound. Its molecular formula is C5H5ClN2O and its molecular weight is 142.56g/mol.
is a colorless liquid, insoluble in water at room temperature, but soluble in organic solvents such as ether and methanol. It has a melting point of -26°C and a boiling point of 156-157°C.
The main use is as an intermediate in organic synthesis. It is often used in the manufacture of organic compounds such as pesticides, pharmaceuticals and pigments. For example, it can be used to synthesize a precursor for the pesticide insecticide Thiamethoxam. In addition, it can also be used to synthesize other compounds containing pyrimidine ring structures, such as intermediates for drugs and pesticides.
The preparation method can be obtained by reacting 2-chloro-5-aminopyrimidine with methanol. Specifically, 2-chloro-5-aminopyrimidine can be first reacted with formic acid Ketal (the product obtained by reacting methanol with formic acid to remove water), and then further processed to obtain calcium.
Regarding safety information, it is less toxic, but it is still necessary to operate safely. Avoid contact with skin and eyes during use, and wear protective gloves and safety glasses if necessary. If you come into contact with it, rinse immediately with water and seek medical help. When stored, it should be kept sealed and stored in a cool, dry place, away from fire and flammable substances. During use and handling, please follow the relevant safety procedures.
