Description
CATO supplies (R)-4-Nitrophenyl 2-aminopropanoate hydrochloride (CAS 81086-57-9), a certified reference material (molecular formula C9H10N2O4HCl, MW 246.65 g/mol) for analytical method development and quality control.
Structurally, (R)-4-Nitrophenyl 2-aminopropanoate hydrochloride (C9H10N2O4HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 246.65 g/mol, it falls into the medium-molecular-weight range. 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), (R)-4-Nitrophenyl 2-aminopropanoate 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.
