3-(4-Oxo-1,2,3-benzotriazin-3(4H)-yl)propanoic acid (CAS 51672-79-8) is a high-purity analytical reference standard with the molecular formula C10H9N3O3 and a molecular weight of 219.20 g/mol.
Structurally, 3-(4-Oxo-1,2,3-benzotriazin-3(4H)-yl)propanoic acid (C10H9N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 219.20 g/mol, it falls into the medium-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.
