Chemical Structure

DL-alpha-Tocopherylacetate CAS 52225-20-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including DL-alpha-Tocopherylacetate.

DL-alpha-Tocopherylacetate (CAS 52225-20-4) is a high-purity analytical reference standard with the molecular formula C31H52O3 and a molecular weight of 472.74 g/mol.

The molecular framework of DL-alpha-Tocopherylacetate (C31H52O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

CATO manufactures DL-alpha-Tocopherylacetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
