Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-2-cyano-N,N-dimethyl-1H-benzo[d]imidazole-1-sulfonamide.
CATO supplies 4-Chloro-2-cyano-N,N-dimethyl-1H-benzo[d]imidazole-1-sulfonamide (CAS 88422-35-9), a certified reference material (molecular formula C10H9ClN4O2S, MW 284.72 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-2-cyano-N,N-dimethyl-1H-benzo[d]imidazole-1-sulfonamide (C10H9ClN4O2S) 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. 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.
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.
