Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 419.65 g/mol gives 1α,25-Dihydroxyvitamin D<SUB>3</SUB> (6,19,19-d<SUB>3</SUB>) solution distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1α,25-Dihydroxyvitamin D<SUB>3</SUB> (6,19,19-d<SUB>3</SUB>) solution (CAS 128723-16-0), molecular formula C27H41D3O3 and molecular weight 419.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1α,25-Dihydroxyvitamin D<SUB>3</SUB> (6,19,19-d<SUB>3</SUB>) solution (C27H41D3O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1α,25-Dihydroxyvitamin D<SUB>3</SUB> (6,19,19-d<SUB>3</SUB>) solution meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
