CATO supplies methyl 3-(N-(4-chloro-3-methylisoxazol-5-yl)sulfamoyl)thiophene-2-carboxylate (CAS 184644-72-2), a certified reference material (molecular formula C10H9ClN2O5S2, MW 336.77 g/mol) for analytical method development and quality control.
methyl 3-(N-(4-chloro-3-methylisoxazol-5-yl)sulfamoyl)thiophene-2-carboxylate (C10H9ClN2O5S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. 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.
As a certified reference material (CRM), methyl 3-(N-(4-chloro-3-methylisoxazol-5-yl)sulfamoyl)thiophene-2-carboxylate 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.
