Compared with other compounds in its class, the molecular weight of 322.36 g/mol gives H-Phe-AMC distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
H-Phe-AMC (CAS 98516-72-4) is a high-purity analytical reference standard with the molecular formula C19H18N2O3 and a molecular weight of 322.36 g/mol.
H-Phe-AMC (C19H18N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
