6-Bromo-1(4H)-phthalazinone(CAS: 75884-70-7)

6-Bromo-1(4H)-phthalazinone (CAS: 75884-70-7) is a crystalline solid with a molecular weight of approximately 215.03 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetic acid. Chemically, it is relatively stable but can undergo bromination reactions under certain conditions. It does not react readily with common reagents but may decompose at high temperatures.

6-Bromo-1(4H)-phthalazinone is typically synthesized through bromination of phthalic anhydride using fuming sulfuric acid as a catalyst. The reaction is carried out under anhydrous conditions to achieve high selectivity and yield. The process requires precise control of temperature and concentration to avoid side reactions and ensure the desired product is formed.

6-Bromo-1(4H)-phthalazinone (CAS: 75884-70-7) is used primarily in the pharmaceutical and polymer industries. It serves as a precursor in the synthesis of various pharmaceutical compounds and can be incorporated into polymer formulations to enhance their properties. Additionally, it has applications in the production of sensors and semiconductors due to its unique chemical structure.

When handling 6-Bromo-1(4H)-phthalazinone (CAS: 75884-70-7), it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize exposure. Spills should be cleaned up immediately using appropriate absorbent materials, and the area should be properly washed down. Always consult the Safety Data Sheet (SDS) for detailed information on handling and storage procedures.
