Chemical Structure

4-(tert-Butyl)-D-phenylalanine CAS 274262-82-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 221.30 g/mol gives 4-(tert-Butyl)-D-phenylalanine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(tert-Butyl)-D-phenylalanine (CAS 274262-82-7) is a high-purity analytical reference standard with the molecular formula C13H19NO2 and a molecular weight of 221.30 g/mol.

Based on its molecular formula C13H19NO2, 4-(tert-Butyl)-D-phenylalanine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.30 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).

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.
