Chemical Structure

2,7-Dimethoxythianthrene CAS 54815-69-9 chemical structure

Description

CATO supplies 2,7-Dimethoxythianthrene (CAS 54815-69-9), a certified reference material (molecular formula C14H12O2S2, MW 276.37 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2,7-Dimethoxythianthrene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2,7-Dimethoxythianthrene 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.
