5 - bromo - 2 - nitro - 3 - hydroxypyridine - Introduction

The chemical formula is C5H3BrN2O3 and the molecular weight is 202.99.

The compound is an organic compound having the form of a light yellow solid or powder. Its melting point is about 181-183°C.

It has a wide range of applications in organic synthesis. It can be used as a pesticide intermediate for the synthesis of some new pesticide compounds. In addition, it can also be used to manufacture dyes and fluorescent dyes.

As for the preparation method, it can be usually synthesized from pyridine as a starting material. First, a nitro group is introduced into pyridine to prepare 2-nitropyridine. Then, the bromine group is introduced into 2-nitropyridine by bromination reaction, and the final product is obtained.

When handling and using, you need to pay attention to safety issues. It is an explosive compound, so it should be kept away from fire and high temperatures. In addition, contact with skin, eyes or inhalation of its dust may cause irritation and injury, so personal protective equipment should be worn during operation and ensure that the operation is carried out in a well-ventilated place.
