Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-Allyl 2-amino-3-(4-hydroxyphenyl)propanoate 4-methylbenzenesulfonate (CAS 125441-05-6) is a high-purity analytical reference standard with the molecular formula C12H15NO3C7H8O3S and a molecular weight of 393.45 g/mol.
Structurally, (S)-Allyl 2-amino-3-(4-hydroxyphenyl)propanoate 4-methylbenzenesulfonate (C12H15NO3C7H8O3S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 393.45 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).
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.
