(2R,3S)-3-((tert-Butoxycarbonyl)amino)-2-hydroxy-3-phenylpropanoic acid CAS 126252-53-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3S)-3-((tert-Butoxycarbonyl)amino)-2-hydroxy-3-phenylpropanoic acid.

(2R,3S)-3-((tert-Butoxycarbonyl)amino)-2-hydroxy-3-phenylpropanoic acid (CAS 126252-53-7), molecular formula C14H19NO5 and molecular weight 281.30 g/mol, is a CATO reference standard with documented purity and traceability.

(2R,3S)-3-((tert-Butoxycarbonyl)amino)-2-hydroxy-3-phenylpropanoic acid (C14H19NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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), (2R,3S)-3-((tert-Butoxycarbonyl)amino)-2-hydroxy-3-phenylpropanoic acid 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.
