Chemical Structure

rac Alpha-Lipoic Acid-d5 CAS 1189471-66-6 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.

rac Alpha-Lipoic Acid-d5 (CAS 1189471-66-6), molecular formula C8H9D5O2S2 and molecular weight 211.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of rac Alpha-Lipoic Acid-d5 (C8H9D5O2S2) is characterized by deuterium isotope labeling, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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 manufactures rac Alpha-Lipoic Acid-d5 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.
