Chemical Structure

5-Chloro-n,n,2-trimethylbenzene-1-sulfonamide CAS 473476-99-2 chemical structure

Description

The occurrence of 5-Chloro-n,n,2-trimethylbenzene-1-sulfonamide 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.

CATO supplies 5-Chloro-n,n,2-trimethylbenzene-1-sulfonamide (CAS 473476-99-2), a certified reference material (molecular formula C9H12ClNO2S, MW 233.72 g/mol) for analytical method development and quality control.

Structurally, 5-Chloro-n,n,2-trimethylbenzene-1-sulfonamide (C9H12ClNO2S) 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 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 233.72 g/mol, it falls into the medium-molecular-weight range. 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.
