6-Bromo-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-a]pyridine CAS 1393330-56-7

Description

The occurrence of 6-Bromo-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-a]pyridine 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.

6-Bromo-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 1393330-56-7), molecular formula C11H7BrN4 and molecular weight 275.10 g/mol, is a CATO reference standard with documented purity and traceability.

6-Bromo-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-a]pyridine (C11H7BrN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
