2-(3,7-Dimethyl-5-oxo-1,5-dihydro-[1,2,4]triazolo[4,3-a]pyrimidin-6-yl)acetic acid (CAS 883550-10-5), molecular formula C9H10N4O3 and molecular weight 222.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(3,7-Dimethyl-5-oxo-1,5-dihydro-[1,2,4]triazolo[4,3-a]pyrimidin-6-yl)acetic acid (C9H10N4O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 222.20 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.
