8-Bromo-5-nitroisoquinoline(CAS: 252861-41-9)

8-Bromo-5-nitroisoquinoline is a crystalline solid with a molecular weight of approximately 256.07 g/mol. It has a low solubility in water (0.17 g/100 mL at 20°C) but is more soluble in organic solvents like methanol and acetone. Chemically, it is highly reactive towards nucleophiles and can undergo substitution reactions. It does not pose a significant fire hazard but can produce toxic fumes when heated or reacted under certain conditions.

8-Bromo-5-nitroisoquinoline is typically synthesized via the nitration of 8-bromoisoquinoline followed by bromination of 5-nitroisoquinoline. This process often involves the use of concentrated nitric acid and sulfuric acid as the nitrating mixture, with careful control of temperature and concentration to achieve high selectivity and yield. Catalytic methods using metal complexes can also be employed for more controlled reactions.

8-Bromo-5-nitroisoquinoline finds application in pharmaceuticals, particularly in the development of potential drug candidates for various diseases. It is also used in the synthesis of organic semiconductors and as a reagent in polymer chemistry for the modification of functional groups. Its use in sensors, though less common, is also explored due to its chemical reactivity.

Handling 8-Bromo-5-nitroisoquinoline requires caution due to its reactivity and potential to produce toxic fumes. Proper personal protective equipment (PPE) including gloves, goggles, and a lab coat should be worn. Work should be conducted in a well-ventilated fume hood. Spills should be cleaned up using absorbent materials and the area should be flushed with water. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
