Compared with other compounds in its class, the molecular weight of 305.80 g/mol gives Benzyl (S)-3-amino-4-phenylbutanoate hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzyl (S)-3-amino-4-phenylbutanoate hydrochloride (CAS 1329063-33-3), molecular formula C17H19NO2HCl and molecular weight 305.80 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H19NO2HCl, Benzyl (S)-3-amino-4-phenylbutanoate hydrochloride contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 305.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
