Compared with other compounds in its class, the molecular weight of 419.43 g/mol gives Z-Phe-pNA distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Z-Phe-pNA (CAS 19647-71-3) is a high-purity analytical reference standard with the molecular formula C23H21N3O5 and a molecular weight of 419.43 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Z-Phe-pNA is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
