Overview of Tamoxifen Citrate as an API

Tamoxifen citrate is a selective estrogen receptor modulator (SERM) utilized in hormone receptor-positive breast cancer cases, both for treatment and risk reduction. Its synthesis involves complex chemical processes demanding stringent quality standards aligned with pharmacopeial specifications, such as USP, EP, or JP.

Given its critical medical role, API sourcing must emphasize quality assurance, regulatory adherence, and supply continuity. The global market for tamoxifen API is concentrated among a handful of geographically dispersed manufacturers with specialized capabilities.
