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.

API Intermediate: The Building Block of Modern Pharmaceuticals
What Is an API Intermediate?
An API intermediate is a chemical compound used in the production of an Active Pharmaceutical Ingredient (API). These intermediates are synthesized during the multi-step process that ultimately leads to the final API — the key component in a pharmaceutical drug. Though not biologically active on their own, pharmaceutical intermediates are critical to ensuring high purity and stability in the final medicine.
Role of API Intermediates in Drug Development
Supporting Efficiency and Consistency
API intermediate manufacturers in India like Jay Fine Chem help streamline the complex synthesis processes involved in drug development. By using high-quality bulk drug intermediates, pharmaceutical companies can reduce production time, improve cost-efficiency, and maintain batch-to-batch consistency. This ensures reliable and safe medication reaches patients globally.
Custom API Manufacturing for Innovation
Jay Fine Chem also excels in custom API manufacturing, enabling tailored solutions for specialized drug formulations. This flexibility is essential for pharmaceutical companies developing innovative therapies or niche products.
