3-Bromoquinoline-5-sulfonyl chloride CAS 33768-83-1

Description

As a certified reference material (CRM), 3-Bromoquinoline-5-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 3-Bromoquinoline-5-sulfonyl chloride (CAS 33768-83-1), a certified reference material (molecular formula C9H5BrClNO2S, MW 306.56 g/mol) for analytical method development and quality control.

3-Bromoquinoline-5-sulfonyl chloride (C9H5BrClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
