Description
Compared with other compounds in its class, the molecular weight of 294.15 g/mol gives ethyl 7-bromo-4-hydroxypyrrolo[2,1-f][1,2,4]triazine-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
ethyl 7-bromo-4-hydroxypyrrolo[2,1-f][1,2,4]triazine-5-carboxylate (CAS 938192-22-4), molecular formula C9H16BrN3O3 and molecular weight 294.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, ethyl 7-bromo-4-hydroxypyrrolo[2,1-f][1,2,4]triazine-5-carboxylate (C9H16BrN3O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 294.15 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.
