Pyridine, 3-bromo-2-methyl-5-nitro- - Introduction

It is an organic compound with the chemical formula C8H6BrN2O2. The following is a description of its nature, use, preparation and safety information:

Nature: It is a yellow crystal with strong ignition point and explosive. It has low solubility at normal temperature and is soluble in organic solvents such as ethanol and ether.

Uses: Often used as an intermediate in organic synthesis. It can be used in the synthesis of nitrogen-containing heterocyclic compounds, drugs and photosensitizers. It is also used as a dye and indicator.

Preparation Method: It can be prepared by reacting 2-methyl -3-aminopyridine with bromine and a nitrating agent. First, 2-methyl-3-aminopyridine is reacted with bromine to obtain 2-methyl-3-bromopyridine, which is then nitrated by reaction with a nitrating agent.

Safety information: It is an explosive and highly flammable compound. Pay attention to safety during operation. Avoid contact with flammable or combustible materials, and also avoid sparks caused by friction, impact or static electricity. Wear suitable protective equipment such as gloves, goggles and masks during operation. If leakage or contact with skin, eyes or inhalation occurs, rinse immediately with plenty of water and seek medical help. Sealed and stored in a cool, dry place, away from fire and flammable materials.
