5-CHLORO-2-PYDRIDINECARBOXYLIC ACID - Introduction

Acid (acid) is an organic compound with the chemical formula C6H4ClNO2.

Nature:
Acid is a white to light yellow crystalline solid with a special smell. It is soluble in some organic solvents, such as ethanol, dimethyl sulfoxide and dichloromethane, but has low solubility in water. It is stable in air and decomposes at high temperatures.

Use:
Acid is an important organic intermediate, which is widely used in the synthesis of other organic compounds. It can be used in the preparation of pesticides, drugs, dyes and coordination compounds.

Preparation Method:
Acid can be synthesized by a variety of methods, commonly used methods include the following two:
1. 2-picolinic acid chloride is reacted with chloroacetic acid to generate the target product with the aid of a catalyst and under appropriate conditions.
2. react 2-pyridyl methanol with carbonic acid chloride, and then hydrolyze with acid to obtain acid.

Safety Information:
The toxicity of acid is low, but it is still necessary to pay attention to safe operation. Avoid direct contact with skin, eyes and respiratory tract, and wear protective gloves, goggles and masks if necessary. Avoid contact with oxidizing agents and flammable substances during use and storage. Should be stored in a dry, well-ventilated place, away from fire. If ingested or inhaled, seek medical attention immediately.
