Chemical Structure

D-Phenylalanine tert-Butyl Ester HCl CAS 3403-25-6 chemical structure

Description

The occurrence of D-Phenylalanine tert-Butyl Ester HCl is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

D-Phenylalanine tert-Butyl Ester HCl (CAS 3403-25-6) is a high-purity analytical reference standard with the molecular formula C13H19NO2HCl and a molecular weight of 257.76 g/mol.

The molecular framework of D-Phenylalanine tert-Butyl Ester HCl (C13H19NO2HCl) 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 its high hydrophobicity (logP), 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
