Chemical Structure
Description
The molecular framework of 2-[(1-Acetyl-2-oxopropyl)thio]-N-cyclohexyl-1H-benzimidazole-1-carboxamide (C19H23N3O3S) 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).
2-[(1-Acetyl-2-oxopropyl)thio]-N-cyclohexyl-1H-benzimidazole-1-carboxamide (CAS 98183-15-4) is a high-purity analytical reference standard with the molecular formula C19H23N3O3S and a molecular weight of 373.47 g/mol.
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.
