Description

Compared with other compounds in its class, the molecular weight of 350.41 g/mol gives (S)-Methyl 2-((tert-Butoxycarbonyl)amino)-3-(4-carbamoyl-2,6-dimethylphenyl)propanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-Methyl 2-((tert-Butoxycarbonyl)amino)-3-(4-carbamoyl-2,6-dimethylphenyl)propanoate (CAS 623950-05-0), a certified reference material (molecular formula C18H26N2O5, MW 350.41 g/mol) for analytical method development and quality control.

Structurally, (S)-Methyl 2-((tert-Butoxycarbonyl)amino)-3-(4-carbamoyl-2,6-dimethylphenyl)propanoate (C18H26N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 350.41 g/mol, it falls into the moderately-high-molecular-weight range. 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.
