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.
1-((1-(Hydroxymethyl)cyclopropyl)methyl)-3-(thiophen-2-ylmethyl)urea (CAS 1257549-01-1), molecular formula C11H16N2O2S and molecular weight 240.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H16N2O2S, 1-((1-(Hydroxymethyl)cyclopropyl)methyl)-3-(thiophen-2-ylmethyl)urea contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
As a certified reference material (CRM), 1-((1-(Hydroxymethyl)cyclopropyl)methyl)-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.
