Chemical Structure

2,3,5,6-Tetrachlorophenol acetate CAS 61925-90-4 chemical structure

Description

The occurrence of 2,3,5,6-Tetrachlorophenol acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,3,5,6-Tetrachlorophenol acetate (CAS 61925-90-4), a certified reference material (molecular formula C8H4Cl4O2, MW 273.93 g/mol) for analytical method development and quality control.

Structurally, 2,3,5,6-Tetrachlorophenol acetate (C8H4Cl4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 273.93 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 2,3,5,6-Tetrachlorophenol 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.
