Chemical Structure

d-alpha-Tocopheryl Retinoate CAS 40516-49-2 chemical structure

Description

As a certified reference material (CRM), d-alpha-Tocopheryl Retinoate 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.

CATO supplies d-alpha-Tocopheryl Retinoate (CAS 40516-49-2), a certified reference material (molecular formula C49H76O3, MW 713.13 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, d-alpha-Tocopheryl Retinoate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 713.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
