Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, N-Fmoc-3-(4-pyridyl)-L-alanine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
N-Fmoc-3-(4-pyridyl)-L-alanine (CAS 169555-95-7) is a high-purity analytical reference standard with the molecular formula C23H20N2O4 and a molecular weight of 388.42 g/mol.
