Chemical Structure
Description
The occurrence of 6-bromo-8-fluoro-2H,3H-[1,2,4]triazolo[4,3-a]pyridine-3-thione is closely related to a nitrile group, sulfur-containing functionality, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-bromo-8-fluoro-2H,3H-[1,2,4]triazolo[4,3-a]pyridine-3-thione (CAS 1427473-77-5), a certified reference material (molecular formula C6H9BrFN3S, MW 254.12 g/mol) for analytical method development and quality control.
6-bromo-8-fluoro-2H,3H-[1,2,4]triazolo[4,3-a]pyridine-3-thione (C6H9BrFN3S) contains a nitrile group, sulfur-containing functionality, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
