149849-92-3 - Introduction
Pyridinium, also known as 2-chloro-4-carboxylic acid pyridine, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: acid is a white to light yellow solid powder.
-Solubility: Soluble in organic solvents such as ketones, ethers and alcohols, insoluble in water.
-Chemical properties: acid is a derivative of pyridine, which has the properties of pyridine and can participate in common organic reactions such as esterification, substitution reactions and electrophilic addition.
Use:
-Pharmaceutical industry: acid can be used as an intermediate for the synthesis of drugs. It plays an important role in the synthesis of many antibacterial drugs, antiviral drugs and anticancer drugs.
-Pesticide field: It can also be used as a raw material for pesticides, used in the production of pesticides and herbicides.
Method:
-or acid can be prepared by reacting pyridine with chloroformic acid in the presence of a base. The specific synthesis method is that pyridine is first dissolved in an alcohol solvent, then chloroformic acid is added, and then an alkali catalyst is added to perform the reaction. After the end of the reaction, the acid product is obtained by distillation or other separation methods.
Safety Information:
-acid is an organic compound with a certain degree of danger. Pay attention to personal protection during operation, avoid direct contact with skin and inhalation of dust.
-This compound may be irritating to the respiratory system, skin and eyes. Therefore, wear appropriate protective gloves, goggles and respiratory protection during operation.
-When storing or handling acid, keep it well ventilated to avoid contact with strong oxidants to avoid dangerous chemical reactions.
Please be sure to operate safely according to the specific situation and experimental conditions, and follow the safety manual and operating instructions of the relevant chemicals.
