Description
CATO manufactures Methyl 2-((5-chloro-2-fluorophenyl)sulfonyl)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.
CATO supplies Methyl 2-((5-chloro-2-fluorophenyl)sulfonyl)acetate (CAS 1779133-08-2), a certified reference material (molecular formula C9H8ClFO4S, MW 266.67 g/mol) for analytical method development and quality control.
Methyl 2-((5-chloro-2-fluorophenyl)sulfonyl)acetate (C9H8ClFO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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).
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.
