Chemical Structure
Description
As a certified reference material (CRM), 4-chloro-3-{[(oxolan-2-yl)methyl]sulfamoyl}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-{[(oxolan-2-yl)methyl]sulfamoyl}benzoic acid (CAS 59210-70-7), a certified reference material (molecular formula C12H20ClNO5S, MW 325.81 g/mol) for analytical method development and quality control.
The molecular framework of 4-chloro-3-{[(oxolan-2-yl)methyl]sulfamoyl}benzoic acid (C12H20ClNO5S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
