Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 333.52 g/mol gives Vitamin A-d5 Acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Vitamin A-d5 Acetate (CAS 1217219-62-9), a certified reference material (molecular formula C22H27D5O2, MW 333.52 g/mol) for analytical method development and quality control.
The molecular framework of Vitamin A-d5 Acetate (C22H27D5O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Vitamin A-d5 Acetate 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.
