Chemical Structure

N-Butyl-4-(2-((2-(cyclopentylamino)-2-oxoethyl)thio)-1H-imidazol-1-yl)benzamide CAS 1207027-17-5 chemical structure

Description

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.

N-Butyl-4-(2-((2-(cyclopentylamino)-2-oxoethyl)thio)-1H-imidazol-1-yl)benzamide (CAS 1207027-17-5), molecular formula C21H28N4O2S and molecular weight 400.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Butyl-4-(2-((2-(cyclopentylamino)-2-oxoethyl)thio)-1H-imidazol-1-yl)benzamide (C21H28N4O2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), N-Butyl-4-(2-((2-(cyclopentylamino)-2-oxoethyl)thio)-1H-imidazol-1-yl)benzamide 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.
