4-cyano-3-methylbenzene-1-sulfonyl chloride CAS 942199-57-7

Description

Compared with other compounds in its class, the molecular weight of 215.66 g/mol gives 4-cyano-3-methylbenzene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-cyano-3-methylbenzene-1-sulfonyl chloride (CAS 942199-57-7) is a high-purity analytical reference standard with the molecular formula C8H6ClNO2S and a molecular weight of 215.66 g/mol.

4-cyano-3-methylbenzene-1-sulfonyl chloride (C8H6ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
