Chemical Structure

Methyl ((4-bromophenoxy)chlorophosphoryl)-L-alaninate CAS 217090-42-1 chemical structure

Description

The occurrence of Methyl ((4-bromophenoxy)chlorophosphoryl)-L-alaninate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl ((4-bromophenoxy)chlorophosphoryl)-L-alaninate (CAS 217090-42-1) is a high-purity analytical reference standard with the molecular formula C10H12BrClNO4P and a molecular weight of 356.54 g/mol.

The molecular framework of Methyl ((4-bromophenoxy)chlorophosphoryl)-L-alaninate (C10H12BrClNO4P) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine/bromine 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. 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.
