Chemical Structure
Description
The molecular framework of N-[(Chloro(phenoxy)phosphoryl)]-L-Alanine Ethyl Ester (C11H15ClNO4P) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
N-[(Chloro(phenoxy)phosphoryl)]-L-Alanine Ethyl Ester (CAS 245078-14-2) is a high-purity analytical reference standard with the molecular formula C11H15ClNO4P and a molecular weight of 291.67 g/mol.
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), N-[(Chloro(phenoxy)phosphoryl)]-L-Alanine Ethyl Ester 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.
