Chemical Structure
Description
1-(5-Oxo-1-(p-tolyl)pyrrolidin-3-yl)-3-(thiophen-2-ylmethyl)urea (CAS 891090-74-7), molecular formula C17H19N3O2S and molecular weight 329.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(5-Oxo-1-(p-tolyl)pyrrolidin-3-yl)-3-(thiophen-2-ylmethyl)urea (C17H19N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 329.42 g/mol, it falls into the moderately-high-molecular-weight range. 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-(5-Oxo-1-(p-tolyl)pyrrolidin-3-yl)-3-(thiophen-2-ylmethyl)urea 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.
