Chemical Structure
Description
CATO supplies 4-(Chlorosulfonyl)naphthalen-1-yl acetate (CAS 58878-79-8), a certified reference material (molecular formula C12H9ClO4S, MW 284.72 g/mol) for analytical method development and quality control.
4-(Chlorosulfonyl)naphthalen-1-yl acetate (C12H9ClO4S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 4-(Chlorosulfonyl)naphthalen-1-yl 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.
