Chemical Structure

3,4,5-Trimethylphenyl acetate CAS 6719-74-0 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 3,4,5-Trimethylphenyl acetate (CAS 6719-74-0), a certified reference material (molecular formula C11H14O2, MW 178.23 g/mol) for analytical method development and quality control.

The molecular framework of 3,4,5-Trimethylphenyl acetate (C11H14O2) 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 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).

CATO manufactures 3,4,5-Trimethylphenyl acetate 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.
