Chemical Structure
Description
The occurrence of 4-(3-Bromo-1H-1,2,4-triazol-1-yl)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(3-Bromo-1H-1,2,4-triazol-1-yl)aniline (CAS 1129540-72-2), molecular formula C8H7BrN4 and molecular weight 239.07 g/mol, is a CATO reference standard with documented purity and traceability.
4-(3-Bromo-1H-1,2,4-triazol-1-yl)aniline (C8H7BrN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
