Chemical Structure
Description
3-[2-(methylamino)ethyl]-2,3-dihydro-1,3-benzoxazol-2-one hydrochloride (CAS 1311314-63-2), molecular formula C10H12N2O2HCl and molecular weight 228.68 g/mol, is a CATO reference standard with documented purity and traceability.
3-[2-(methylamino)ethyl]-2,3-dihydro-1,3-benzoxazol-2-one hydrochloride (C10H12N2O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-[2-(methylamino)ethyl]-2,3-dihydro-1,3-benzoxazol-2-one hydrochloride 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.
