2,6-Dibromo-3-nitropyridine(CAS: 55304-80-8)

2,6-Dibromo-3-nitropyridine is a crystalline solid with a molecular weight of approximately 283.03 g/mol. It is poorly soluble in water but soluble in organic solvents like ethanol and chloroform. Chemically, it is relatively stable but can undergo nitration and bromination reactions under certain conditions. It has a melting point of around 164-166°C and a boiling point of about 318°C at 760 mmHg.

2,6-Dibromo-3-nitropyridine can be synthesized through a nitration reaction of 2,6-dibromopyridine with nitric acid in the presence of concentrated sulfuric acid as a catalyst. The reaction is carried out at high temperatures to ensure high yields. The key parameters include temperature control and the use of protective equipment to handle the corrosive and potentially toxic reactants.

2,6-Dibromo-3-nitropyridine is used in the pharmaceutical industry for the synthesis of certain medicinal compounds. It also finds applications in the production of dyes and pigments, and as a precursor in the semiconductor industry for the development of novel electronic materials. Its role in sensors and other specialized chemical applications is also recognized.

When handling 2,6-Dibromo-3-nitropyridine, it is essential to follow strict safety protocols. Wear appropriate personal protective equipment (PPE) including gloves, safety goggles, and a lab coat. Work in a well-ventilated area or a fume hood to minimize exposure to the vapors. Ensure proper storage in a cool, dry place away from incompatible materials. In case of a spill, immediately clean it up with appropriate absorbent materials and consult the Material Safety Data Sheet (MSDS/SDS) for further instructions.
