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-(3-Chlorophenyl)-2-((5-(hydroxymethyl)-1-(2-(isopropylamino)-2-oxoethyl)-1H-imidazol-2-yl)thio)acetamide (CAS 921524-15-4), molecular formula C17H21ClN4O3S and molecular weight 396.89 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, N-(3-Chlorophenyl)-2-((5-(hydroxymethyl)-1-(2-(isopropylamino)-2-oxoethyl)-1H-imidazol-2-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), N-(3-Chlorophenyl)-2-((5-(hydroxymethyl)-1-(2-(isopropylamino)-2-oxoethyl)-1H-imidazol-2-yl)thio)acetamide 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.
