Chemical Structure
Description
5-(n,n-Diethylsulfamoyl)thiophene-2-sulfonyl chloride (CAS 1306607-15-7) is a high-purity analytical reference standard with the molecular formula C8H12ClNO4S3 and a molecular weight of 317.83 g/mol.
5-(n,n-Diethylsulfamoyl)thiophene-2-sulfonyl chloride (C8H12ClNO4S3) contains an amide group, a sulfone group, a carboxylic acid 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.
CATO manufactures 5-(n,n-Diethylsulfamoyl)thiophene-2-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
