Understanding 5-Cyanophthalide: A Key Intermediate in Modern API Synthesis
5-Cyanophthalide is an important chemical intermediate widely recognized for its role in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs). Classified under phthalide derivatives, this compound is known for its high reactivity and purity requirements, making it critical in regulated drug manufacturing processes.
Chemically identified by its CAS number 82104-74-3, 5-Cyanophthalide has the molecular formula and typically appears as a white to off-white crystalline solid. The presence of a cyano group attached to a phthalide backbone allows it to serve as a versatile building block for various complex organic molecules, including antidepressants and psychoactive compounds.
One of the most notable applications of 5-Cyanophthalide is in the synthesis of Citalopram KSM (Key Starting Material), which is crucial in producing the widely prescribed antidepressant Citalopram. Given the drug’s popularity and therapeutic importance, the demand for high-quality 5-Cyanophthalide has grown significantly, especially in regions with a strong pharmaceutical manufacturing base like India.
