Chemical Structure

Z-Phe-NH? CAS 4801-80-3 chemical structure

Description

Z-Phe-NH? (CAS 4801-80-3), molecular formula C17H18N2O3 and molecular weight 298.34 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H18N2O3, Z-Phe-NH? contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
