Description

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.

3-Bromo-1-(phenylsulfonyl)-1H-pyrrole-2-carboxylic acid (CAS 2387602-47-1), molecular formula C11H8BrNO4S and molecular weight 330.15 g/mol, is a CATO reference standard with documented purity and traceability.

3-Bromo-1-(phenylsulfonyl)-1H-pyrrole-2-carboxylic acid (C11H8BrNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 3-Bromo-1-(phenylsulfonyl)-1H-pyrrole-2-carboxylic 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.
