Diethylstilbestrol (CAS 56-53-1)/ API

Diethylstilbestrol (CAS 56-53-1) is a high-purity pharmaceutical API classified as a potent synthetic estrogen, featuring a non-steroidal diphenylethylene molecular structure with strong affinity for estrogen receptors. Unlike endogenous estrogens, it offers stable oral bioavailability and prolonged half-life, exerting consistent hormonal regulatory effects by mimicking natural estrogen activity. This API presents as a white to off-white crystalline powder with excellent solubility in organic solvents, facilitating flexible formulation development.

It caters to the core needs of hormonal therapy manufacturers, veterinary pharmaceutical developers, and research institutions. Widely applied in veterinary hormone therapy (e.g., livestock reproductive regulation) and biomedical research on estrogen-related pathways, it aligns with demand for cost-effective, high-potency synthetic estrogen raw materials. Produced under strict GMP standards, each batch undergoes rigorous purity, morphology, and potency testing to meet international quality requirements, ensuring reliability for specialized applications. For businesses prioritizing synthetic estrogen solutions, this Diethylstilbestrol API serves as a critical raw material for advancing hormonal and veterinary pharmaceutical development.
