Used as a key intermediate in the synthesis of progesterone derivatives for immunoassay development. Enables conjugation to carrier proteins for generating anti-progesterone antibodies in diagnostic applications. Employed in hormone research and development of hormone detection kits. Facilitates the production of labeled hormones for radioimmunoassays (RIA) and enzyme-linked immunosorbent assays (ELISA). Supports studies in reproductive health, fertility monitoring, and endocrine function evaluation.
