Chemical Structure
Description
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.
Fmoc-Tyr(PO3H2)-OH (CAS 147762-53-6) is a high-purity analytical reference standard with the molecular formula C24H22NO8P and a molecular weight of 483.41 g/mol.
Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, Fmoc-Tyr(PO3H2)-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 483.41 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).
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.
