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.
Methyl (3r)-4-amino-3-{[(benzyloxy)carbonyl]amino}butanoate hydrochloride (CAS 845909-53-7), molecular formula C13H18N2O4HCl and molecular weight 302.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl (3r)-4-amino-3-{[(benzyloxy)carbonyl]amino}butanoate hydrochloride (C13H18N2O4HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Methyl (3r)-4-amino-3-{[(benzyloxy)carbonyl]amino}butanoate 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.
