Bromfenac sodium hydrate(CAS: 120638-55-3)

Bromfenac sodium hydrate is a white or off-white crystalline powder with a molecular weight of approximately 364.8 g/mol. It is slightly soluble in water and almost insoluble in organic solvents. Chemically, it is a salt of bromfenac and sodium, and it displays general reactivity typical of carboxylic acid salts, including potential hydrolytic instability under alkaline conditions.

Bromfenac sodium hydrate is typically synthesized by reacting bromfenac, a 1,2-benzothiazine-3-carboxylic acid derivative, with sodium hydroxide in a suitable solvent. The reaction involves esterification followed by base hydrolysis to obtain the sodium salt. Common synthetic methods include phase transfer catalysis and use of organic bases to improve selectivity and yield.

Bromfenac sodium hydrate is primarily used in the pharmaceutical industry as an anti-inflammatory and analgesic agent. It is also explored for use in polymer and sensor applications due to its chemical stability and reactivity. In the semiconductor industry, it is considered for its potential use in certain manufacturing processes.

When handling Bromfenac sodium hydrate, it is important to use personal protective equipment (PPE) such as gloves and goggles. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbent materials, and the area should be well-ventilated. Safety data sheets (SDS) should be consulted for detailed handling and disposal instructions.
