6-oxo-1,6-dihydropyridine-2-carboxylic acid - Introduction
6-hydroxyacrylic acid (6-hydroxyacrylic acid), also known as 6-Pyridin-2-olcarboxylic acid, is an organic compound.
Nature:
-Appearance: 6-hydroxyypicolinic acid is a colorless or slightly yellow crystal or crystalline powder.
-Solubility: Soluble in water, alcohols and Ether solvents.
-Chemical properties: It is a weak acid that can react with alkali to form the corresponding salt.
Use:
-Chemical reagent: 6-hydroxyypicolinic acid is often used as a ligand of coordination compounds and can be used to synthesize metal complexes.
-Drug intermediate: It can be used to synthesize drugs containing pyridine ring structure.
Method:
The preparation of 6-hydroxypicolinic acid can be carried out by the following methods:
1. Pyridine and methanol react in the presence of oxygen to obtain 6-hydroxy-2-picolinic acid. Then the esterification reaction was carried out under alkaline conditions to obtain 6-hydroxyypicolinic acid.
Safety Information:
-6-hydroxyicolinic acid may be irritating to the eyes, skin and respiratory system, please avoid direct contact.
-When using, do a good job in laboratory safety operations, wear appropriate personal protective equipment, such as laboratory gloves and goggles.
-storage should be sealed, avoid contact with oxygen, acid and alkali.
-In case of inhalation or misuse, please seek medical attention.
