Chemical Structure
Description
The occurrence of Methyl 3-(1-methyl-1H-1,2,4-triazol-5-yl)-3-oxopropanoate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 3-(1-methyl-1H-1,2,4-triazol-5-yl)-3-oxopropanoate (CAS 1007585-93-4), molecular formula C7H9N3O3 and molecular weight 183.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 3-(1-methyl-1H-1,2,4-triazol-5-yl)-3-oxopropanoate (C7H9N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 183.16 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).
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.
