Chemical Structure

tert-Butyl (S)-3-Amino-4-phenylbutanoate CAS 120686-17-1 chemical structure

Description

The occurrence of tert-Butyl (S)-3-Amino-4-phenylbutanoate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies tert-Butyl (S)-3-Amino-4-phenylbutanoate (CAS 120686-17-1), a certified reference material (molecular formula C14H21NO2, MW 235.32 g/mol) for analytical method development and quality control.

Structurally, tert-Butyl (S)-3-Amino-4-phenylbutanoate (C14H21NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 235.32 g/mol, it falls into the medium-molecular-weight range. 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.
