Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(1-Benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)-4-chloro-N-(4-chlorobenzenesulfonyl)benzene-1-sulfonamide.
CATO supplies N-(1-Benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)-4-chloro-N-(4-chlorobenzenesulfonyl)benzene-1-sulfonamide (CAS 478033-04-4), a certified reference material (molecular formula C26H21Cl2N3O4S2, MW 574.50 g/mol) for analytical method development and quality control.
Structurally, N-(1-Benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)-4-chloro-N-(4-chlorobenzenesulfonyl)benzene-1-sulfonamide (C26H21Cl2N3O4S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 574.50 g/mol, it falls into the moderately-high-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.
CATO manufactures N-(1-Benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)-4-chloro-N-(4-chlorobenzenesulfonyl)benzene-1-sulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
