Chemical Structure

all-trans-Retinol-d5 CAS 1185244-58-9 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.

CATO supplies all-trans-Retinol-d5 (CAS 1185244-58-9), a certified reference material (molecular formula C20H25D5O, MW 291.48 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, all-trans-Retinol-d5 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

As a certified reference material (CRM), all-trans-Retinol-d5 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.
