2-Cyano-1-benzothiophene-3-sulfonyl chloride CAS 1334626-84-4

Description

Compared with other compounds in its class, the molecular weight of 257.72 g/mol gives 2-Cyano-1-benzothiophene-3-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Cyano-1-benzothiophene-3-sulfonyl chloride (CAS 1334626-84-4), molecular formula C9H4ClNO2S2 and molecular weight 257.72 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Cyano-1-benzothiophene-3-sulfonyl chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
