Chemical Structure
Description
The occurrence of N-[2-(3,5-Dimethyl-1H-pyrazole-1-carbonyl)thiophen-3-yl]-N-methyl-4-propylbenzene-1-sulfonamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-[2-(3,5-Dimethyl-1H-pyrazole-1-carbonyl)thiophen-3-yl]-N-methyl-4-propylbenzene-1-sulfonamide (CAS 1325306-95-3), a certified reference material (molecular formula C20H23N3O3S2, MW 417.54 g/mol) for analytical method development and quality control.
The molecular framework of N-[2-(3,5-Dimethyl-1H-pyrazole-1-carbonyl)thiophen-3-yl]-N-methyl-4-propylbenzene-1-sulfonamide (C20H23N3O3S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-[2-(3,5-Dimethyl-1H-pyrazole-1-carbonyl)thiophen-3-yl]-N-methyl-4-propylbenzene-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.
