Chemical Structure
Description
CATO supplies Butyl 4-(((4-bromophenyl)sulfonyl)oxy)benzoate (CAS 331462-35-2), a certified reference material (molecular formula C17H17BrO5S, MW 413.28 g/mol) for analytical method development and quality control.
Butyl 4-(((4-bromophenyl)sulfonyl)oxy)benzoate (C17H17BrO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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.
CATO manufactures Butyl 4-(((4-bromophenyl)sulfonyl)oxy)benzoate 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.
