Used as an intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the production of loxoprofen, a prodrug that exhibits analgesic and antipyretic effects. Its calcium salt form enhances stability and improves handling during pharmaceutical manufacturing. The compound plays a key role in enabling efficient drug formulation due to its favorable crystallinity and water solubility provided by the dihydrate structure. It is primarily utilized in solid dosage forms such as tablets, where consistent purity and flow properties are essential for tablet compression.
