Chemical Structure
Description
1-(4-Aminophenyl)-3-(propan-2-yl)urea (CAS 70826-93-6), molecular formula C10H15N3O and molecular weight 193.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H15N3O, 1-(4-Aminophenyl)-3-(propan-2-yl)urea contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(4-Aminophenyl)-3-(propan-2-yl)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.
