Description
As a certified reference material (CRM), [4-(N,N-Dimethylsulfamoyl)phenyl]methanesulfonyl 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.
[4-(N,N-Dimethylsulfamoyl)phenyl]methanesulfonyl Chloride (CAS 1503705-58-5) is a high-purity analytical reference standard with the molecular formula C9H12ClNO4S2 and a molecular weight of 297.78 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, [4-(N,N-Dimethylsulfamoyl)phenyl]methanesulfonyl Chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 297.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
