Chemical Structure

Acetic anhydride-d6 CAS 16649-49-3 chemical structure

Description

The occurrence of Acetic anhydride-d6 is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Acetic anhydride-d6 (CAS 16649-49-3), a certified reference material (molecular formula C4D6O3, MW 108.13 g/mol) for analytical method development and quality control.

The molecular framework of Acetic anhydride-d6 (C4D6O3) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. 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 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).

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 manufactures Acetic anhydride-d6 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.
