Chemical Structure
Description
The occurrence of 1-[1-[2-Oxo-2-(1,2,5-trimethyl-3-pyrrolyl)ethyl]-4-piperidinyl]-1H-benzo[d]imidazol-2(3H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-[1-[2-Oxo-2-(1,2,5-trimethyl-3-pyrrolyl)ethyl]-4-piperidinyl]-1H-benzo[d]imidazol-2(3H)-one (CAS 924108-75-8), a certified reference material (molecular formula C21H26N4O2, MW 366.46 g/mol) for analytical method development and quality control.
The molecular framework of 1-[1-[2-Oxo-2-(1,2,5-trimethyl-3-pyrrolyl)ethyl]-4-piperidinyl]-1H-benzo[d]imidazol-2(3H)-one (C21H26N4O2) is characterized by a steroid core, an amide 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.
As a certified reference material (CRM), 1-[1-[2-Oxo-2-(1,2,5-trimethyl-3-pyrrolyl)ethyl]-4-piperidinyl]-1H-benzo[d]imidazol-2(3H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
