Chemical Structure
Description
7-BROMO-2-(4-METHOXYPHENYL)-[1,2,4]TRIAZOLO[1,5-A]PYRIDINE (CAS 1893211-85-2), molecular formula C13H10BrN3O and molecular weight 304.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-BROMO-2-(4-METHOXYPHENYL)-[1,2,4]TRIAZOLO[1,5-A]PYRIDINE (C13H10BrN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 304.14 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
