Description
Compared with other compounds in its class, the molecular weight of 410.42 g/mol gives (R)-2-(Fmoc-amino)-3-[[(allyloxy)carbonyl]amino]propanoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-2-(Fmoc-amino)-3-[[(allyloxy)carbonyl]amino]propanoic Acid (CAS 178924-05-5), molecular formula C22H22N2O6 and molecular weight 410.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-2-(Fmoc-amino)-3-[[(allyloxy)carbonyl]amino]propanoic Acid (C22H22N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 410.42 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
