Description
Compared with other compounds in its class, the molecular weight of 271.74 g/mol gives 5-cyano-3-methyl-1-benzothiophene-2-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-cyano-3-methyl-1-benzothiophene-2-sulfonyl chloride (CAS 1030857-85-2) is a high-purity analytical reference standard with the molecular formula C10H6ClNO2S2 and a molecular weight of 271.74 g/mol.
The molecular framework of 5-cyano-3-methyl-1-benzothiophene-2-sulfonyl chloride (C10H6ClNO2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-cyano-3-methyl-1-benzothiophene-2-sulfonyl 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.
