Description

3-Desoxyvitamin D3 is a key intermediate and reference standard in the synthesis and research of vitamin D analogs. This compound is crucial for pharmaceutical development, particularly in the study of bone metabolism, calcium regulation, and cell differentiation. It is primarily utilized by research institutions, pharmaceutical manufacturers, and fine chemical suppliers engaged in the production of advanced vitamin D derivatives and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A critical building block in the multi-step synthesis of novel vitamin D3 analogs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference standard and precursor in metabolic pathway studies related to vitamin D function and receptor binding.
• Reference Material: Serves as a high-purity calibration standard for analytical methods (HPLC, LC-MS) in quality control laboratories.
• Nutraceutical Development: Employed in R&D for creating advanced dietary supplements targeting bone and immune health.
• Academic Research: A valuable tool for universities and research institutes studying endocrinology, oncology, and dermatology related to vitamin D signaling.

Quality Control

Our 3-Desoxyvitamin D3 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR spectroscopy, and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, ensuring traceability and compliance with customer specifications for research and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants or an inert atmosphere.
