Description

10-Ketovitamin D3 is a key intermediate in the synthesis of biologically active vitamin D analogs and other high-value steroidal compounds. This compound matters for its role in enabling precise chemical modifications to the vitamin D backbone, which is critical for developing novel pharmaceuticals and research tools. It is primarily needed by manufacturers in the pharmaceutical, nutraceutical, and fine chemical synthesis industries for producing advanced active pharmaceutical ingredients (APIs) and reference standards.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of calcitriol analogs and other vitamin D receptor modulators.
• Fine Chemical Synthesis: Used in research and development for creating novel steroidal structures with potential therapeutic activity.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in pharmaceutical laboratories.
• Biochemical Research: Employed in metabolic pathway studies to understand vitamin D metabolism and function.
• Nutraceutical Development: Investigated for use in the development of advanced vitamin D-based nutritional supplements.
