Chemical Structure

9,10-Dioxo-9,10-dihydroanthracene-2-sulfonyl chloride CAS 2381-23-9 chemical structure

Description

9,10-Dioxo-9,10-dihydroanthracene-2-sulfonyl chloride (CAS 2381-23-9) is a high-purity analytical reference standard with the molecular formula C14H7ClO4S and a molecular weight of 306.72 g/mol.

The molecular framework of 9,10-Dioxo-9,10-dihydroanthracene-2-sulfonyl chloride (C14H7ClO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 9,10-Dioxo-9,10-dihydroanthracene-2-sulfonyl chloride 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.
