Description
CATO manufactures 4-Bromo-3-nitrobenzenesulfonic acid 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 4-Bromo-3-nitrobenzenesulfonic acid (CAS 584-49-6), a certified reference material (molecular formula C6H4BrNO5S, MW 282.07 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-3-nitrobenzenesulfonic acid (C6H4BrNO5S) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
