Chemical Structure

Methyl 3-((2R)-2-Hydroxy-4-(((((S)-1-methoxy-1-oxopropan-2-yl)amino)(phenoxy)phosphoryl)oxy)-3,3-dimethylbutanamido)propanoate CAS 1858268-66-2 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.

CATO supplies Methyl 3-((2R)-2-Hydroxy-4-(((((S)-1-methoxy-1-oxopropan-2-yl)amino)(phenoxy)phosphoryl)oxy)-3,3-dimethylbutanamido)propanoate (CAS 1858268-66-2), a certified reference material (molecular formula C20H31N2O9P, MW 474.44 g/mol) for analytical method development and quality control.

Based on its molecular formula C20H31N2O9P, Methyl 3-((2R)-2-Hydroxy-4-(((((S)-1-methoxy-1-oxopropan-2-yl)amino)(phenoxy)phosphoryl)oxy)-3,3-dimethylbutanamido)propanoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 474.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), Methyl 3-((2R)-2-Hydroxy-4-(((((S)-1-methoxy-1-oxopropan-2-yl)amino)(phenoxy)phosphoryl)oxy)-3,3-dimethylbutanamido)propanoate 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.
