6,6'-Dibromo-2,2'-bipyridine(CAS: 49669-22-9)

6,6'-Dibromo-2,2'-bipyridine (CAS: 49669-22-9) is a crystalline solid with a molecular weight of approximately 324.07 g/mol. It has low water solubility, with a solubility of about 0.02 g/L at 25°C. This compound exhibits good stability in air but is reactive towards reducing agents. It is commonly used as a ligand in coordination chemistry and as a dopant in organic electronics.

6,6'-Dibromo-2,2'-bipyridine is typically synthesized through the coupling of 2-bromo-1,1'-bipyridine with itself using a coupling agent such as polyphosphoric acid or triphenylphosphine. The reaction is carried out in a solvent like acetic acid, and the product is isolated via filtration and recrystallization. The yield is generally around 70-80%.

6,6'-Dibromo-2,2'-bipyridine (CAS: 49669-22-9) is primarily used in the pharmaceutical industry for developing metal-based drugs and in the electronics industry as a dopant in organic semiconductors. It is also utilized in polymer chemistry for the preparation of conductive polymers and in the manufacturing of sensors for detecting toxic gases.

When handling 6,6'-Dibromo-2,2'-bipyridine (CAS: 49669-22-9), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood due to its potential reactivity. Spills should be handled carefully, and the material safety data sheet (MSDS) should be consulted for specific spill cleanup procedures. Storage should be in a cool, dry place, away from heat sources and oxidizers.
