Description

Isovitamin D3 CAS NO 42607-12-5 is a synthetic analog of vitamin D, specifically a stereoisomer of cholecalciferol. This compound is significant for research and development in the life sciences, offering a precise tool for studying vitamin D receptor (VDR) interactions and metabolic pathways. It is primarily needed by pharmaceutical R&D teams, academic researchers, and manufacturers of high-purity biochemical standards.

Application

• Pharmaceutical Research & Development: A key intermediate or reference standard in the synthesis and study of novel vitamin D analogs and metabolites.
• Biochemical Studies: Used to investigate the structure-activity relationship (SAR) of vitamin D and its interaction with the Vitamin D Receptor (VDR).
• Reference Standard: Serves as a high-purity calibration standard in analytical methods such as HPLC and LC-MS for quality control of vitamin D-related products.
• Nutritional Science Research: Employed in metabolic studies to understand the specific biological effects of different vitamin D isomers.
• Academic Research: Utilized in university and institutional labs for fundamental research on calcium homeostasis, bone health, and endocrine signaling.
