5-Cyano-2-methyl-benzenesulfonylchloride CAS 372198-49-7

Description

The occurrence of 5-Cyano-2-methyl-benzenesulfonylchloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Cyano-2-methyl-benzenesulfonylchloride (CAS 372198-49-7), molecular formula C8H6ClNO2S and molecular weight 215.66 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Cyano-2-methyl-benzenesulfonylchloride (C8H6ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 215.66 g/mol, it falls into the medium-molecular-weight range. 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.
