Chemical Structure

1α-Hydroxyprevitamin D2 CAS 127264-18-0 chemical structure

Description

The molecular framework of 1α-Hydroxyprevitamin D2 (C28H44O2) is characterized by 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).

CATO supplies 1α-Hydroxyprevitamin D2 (CAS 127264-18-0), a certified reference material (molecular formula C28H44O2, MW 412.65 g/mol) for analytical method development and quality control.

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-Hydroxyprevitamin D2 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.
