Description

4-Pregnene-3,20-Dione 3-[o-Carboxymethyl]Oxime is a chemically modified steroid derivative, specifically an oxime conjugate of progesterone. This compound is a critical pharmaceutical intermediate and a valuable reference standard for analytical and research purposes. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and manufacturers of diagnostic reagents.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs) and hormone analogs.
• Analytical Reference Standard: Used for method development, calibration, and quality control in HPLC, LC-MS, and other chromatographic analyses within pharmaceutical quality assurance labs.
• Biochemical Research: Employed in academic and industrial research to study steroid hormone metabolism, receptor binding, and the development of immunoassays.
• Diagnostic Reagent Manufacturing: Acts as a hapten for the production of antibodies used in enzyme-linked immunosorbent assays (ELISA) and other immuno-diagnostic kits.
• Process Development: Used in scaling up synthetic routes for steroid derivatives in pilot plants and commercial manufacturing settings.
