(S)-2-((S)-2-Amino-5-guanidinopentanamido)-3-phenylpropanoic acid compound with acetic acid (1:1) (CAS 79220-29-4), molecular formula C15H23N5O3C2H4O2 and molecular weight 381.43 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-2-((S)-2-Amino-5-guanidinopentanamido)-3-phenylpropanoic acid compound with acetic acid (1:1) (C15H23N5O3C2H4O2) contains a flavonoid 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 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.
