Import Bicalutamide & Intermediate — Buy in Bulk from Supplier in China

Bicalutamide is a non-steroidal antiandrogen active pharmaceutical ingredient used primarily in the treatment of prostate cancer, with this offering from Hangzhou Hysen Pharma also including its associated intermediate. The compound carries CAS number 90357-06-5 and the molecular formula C18H14F4N2O4S, indicating a fluorinated anilide structure with four fluorine atoms and a sulphonyl group critical to its receptor-binding activity. The material is described as white or off-white in appearance, a standard visual indicator for this API grade. Hangzhou Hysen Pharma sources this as an imported-tier supplier with harbour trust status, based at Gudun Road in Hangzhou's Zhejiang province.

The chemical synthesis of bicalutamide typically proceeds through a multi-step route involving fluorinated intermediates, with the final product requiring stringent control of stereochemistry and residual solvents. Standard pharmaceutical grades target purity levels of 99.5% or higher by HPLC, with specific limits on related substances including the R-enantiomer and process impurities. Typical specifications include water content below 0.5% (Karl Fischer), residue on ignition below 0.1%, and heavy metals below 20 ppm. The intermediate component of this offering likely refers to key precursors such as 4-cyano-3-(4-fluorophenyl)-2-hydroxy-2-methylthiopropanilide or analogous fluorinated building blocks used in commercial production routes.

Primary buyers include generic pharmaceutical manufacturers, contract research organisations, and specialist API formulators serving oncology markets. Bicalutamide is formulated as 50 mg oral tablets, often in combination with luteinising hormone-releasing hormone analogues. Import buyers should verify the specific CoA parameters, retest date, and whether the offering is the racemate or enantiomerically enriched form, as regulatory requirements differ by market. Storage typically requires controlled room temperature conditions with protection from moisture and light.
