Capecitabine

Capecitabine is an antineoplastic agent supplied as a white powder with a molecular formula of C15H22FN3O6 and a formula weight of 359.35 g/mol. Its CAS number is 154361-50-9, with a melting point range of 119-121°C and an assay purity of 99%. The compound is used as an active pharmaceutical ingredient (API) in oncology treatments, particularly for colorectal and breast cancers.

The chemical structure of capecitabine includes a fluorine atom, contributing to its mechanism as a prodrug of 5-fluorouracil, which interferes with DNA synthesis in cancer cells. Standard pharmaceutical-grade capecitabine typically meets USP or EP monograph specifications for identity, purity, and residual solvents. Typical moisture content for the powder is below 0.5%, and particle size distribution is controlled to ensure consistent dissolution profiles.

This API is primarily sourced by pharmaceutical manufacturers for oral solid dosage formulations, such as tablets. Buyers should confirm packaging requirements, as the supplier offers flexible options tailored to demand. The product is shipped under controlled conditions to maintain stability, with storage recommendations at 2-8°C to prevent degradation. Importers should verify compliance with local regulatory standards for API handling and distribution.

Nanjing Chemipioneer Pharma & Tech Co., Ltd. is based in Nanjing, China, with its registered address at No.5 Xinke 1St Road, Nanjing 210000. The company operates as an imported-tier supplier, specialising in pharmaceutical intermediates and APIs, including capecitabine. Its profile indicates a focus on chemical and pharmaceutical technology, with no additional verification signals or response metrics currently available.

The supplier’s listing for capecitabine provides essential details such as CAS number, molecular formula, and assay purity, but lacks additional operational data like production capacity, certifications, or export history. Buyers should directly confirm the company’s ability to meet specific regulatory or volume requirements, as the profile does not disclose these parameters. The absence of response rate or average response time suggests limited engagement metrics at present.
