4-(2-ethoxyethoxy)benzene-1-sulfonyl chloride CAS 264624-20-6

Description

CATO supplies 4-(2-ethoxyethoxy)benzene-1-sulfonyl chloride (CAS 264624-20-6), a certified reference material (molecular formula C10H13ClO4S, MW 264.73 g/mol) for analytical method development and quality control.

4-(2-ethoxyethoxy)benzene-1-sulfonyl chloride (C10H13ClO4S) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
