Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
1,25-Dihydroxy Vitamin D2-d (CAS 1261254-46-9), molecular formula C28H41D3O3 and molecular weight 431.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,25-Dihydroxy Vitamin D2-d (C28H41D3O3) is characterized by deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 1,25-Dihydroxy Vitamin D2-d under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
