Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.66 g/mol gives 4-Cyanothiophene-3-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Cyanothiophene-3-sulfonyl chloride (CAS 112472-37-4) is a high-purity analytical reference standard with the molecular formula C5H2ClNO2S2 and a molecular weight of 207.66 g/mol.
4-Cyanothiophene-3-sulfonyl chloride (C5H2ClNO2S2) contains an amide group, a sulfone group, a carboxylic acid 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.
CATO manufactures 4-Cyanothiophene-3-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.
