1H-1,2,3-TRIAZOLO[4,5-B]PYRIDINE Chemical Properties,Uses,Production

Uses

1H-1,2,3-Triazolo[4,5-b]pyridine (1,2,3-Triazolo(5,4-b)pyridine) may be used:

  • as starting reagent in the synthesis of 2,4,8,10-tetranitro-5H-pyrido[3″,2″:4′,5′] [1,2,3] triazolo [1′,2′:1,2] [1,2,3]- triazolo [5,4-b]-pyridin-6-ium inner salt
  • in the pesticide synthesis
  • as an entry to mesoionic heteropentalene derivatives

General Description

1H-1,2,3-Triazolo[4,5-b]pyridine belongs to the class of triazolopyridine. It reacts with europium under solvothermal conditions in pyridine to yield the homoleptic framework containing EuII centers that are icosahedrally coordinated by the 12 nitrogen atoms of six chelating ligands. The surface-enhanced Raman (SER) spectra of 1H-1,2,3-triazolo[4,5-b]pyridine adsorbed on silver hydrosols is studied in the region 3500-100cm-1.
