Description

Compared with other compounds in its class, the molecular weight of 289.56 g/mol gives 2,5-Dichloro-4-ethoxybenzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5-Dichloro-4-ethoxybenzenesulfonyl chloride (CAS 1152505-37-7), molecular formula C8H7Cl3O3S and molecular weight 289.56 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Dichloro-4-ethoxybenzenesulfonyl chloride (C8H7Cl3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
