Description

19-Hydroxypregnenolone is a key steroid intermediate and a metabolite in the biosynthesis of various steroid hormones. This compound is of significant interest in pharmaceutical research and development, particularly for the synthesis of more complex steroid derivatives. It serves as a critical building block for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require high-purity steroid precursors for drug discovery and production.

Application

• Pharmaceutical Intermediate: A crucial precursor in the multi-step synthesis of active pharmaceutical ingredients (APIs) for steroid-based therapies.
• Biochemical Research: Used as a standard or reagent in studies investigating steroidogenesis, enzyme activity, and metabolic pathways.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in pharmaceutical laboratories.
• Fine Chemical Synthesis: Employed as a starting material for the custom synthesis of novel steroid analogs and derivatives in R&D settings.
• Endocrinology Studies: Utilized in in-vitro and in-vivo research to understand the role of steroid hormone precursors.
