2,4-dimethyl-5-nitrobenzene-1-sulfonyl chloride CAS 71474-35-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-dimethyl-5-nitrobenzene-1-sulfonyl chloride.

CATO supplies 2,4-dimethyl-5-nitrobenzene-1-sulfonyl chloride (CAS 71474-35-6), a certified reference material (molecular formula C8H8ClNO4S, MW 249.67 g/mol) for analytical method development and quality control.

The molecular framework of 2,4-dimethyl-5-nitrobenzene-1-sulfonyl chloride (C8H8ClNO4S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
