Chemical Structure
Description
As a certified reference material (CRM), 4-Chloro-3-[[(2-chlorophenyl)-2-propen-1-ylamino]sulfonyl]benzoic acid 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 4-Chloro-3-[[(2-chlorophenyl)-2-propen-1-ylamino]sulfonyl]benzoic acid (CAS 380436-74-8), a certified reference material (molecular formula C16H13Cl2NO4S, MW 386.25 g/mol) for analytical method development and quality control.
4-Chloro-3-[[(2-chlorophenyl)-2-propen-1-ylamino]sulfonyl]benzoic acid (C16H13Cl2NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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.
