Indazole Chemical Properties,Uses,Production
Chemical Properties
white to beige needle-like crystalline powder
Uses
1H-Indazole is used in organic synthesis, it can react with butyryl chloride and 1-butyryl-1H-indazole. It is also used in synthesis of several small molecule inhibitors as potential cancer therapeutics.
Definition
ChEBI: 1H-indazole is an indazole. It is a tautomer of a 2H-indazole.
Synthesis Reference(s)
Journal of the American Chemical Society, 79, p. 5242, 1957 DOI: 10.1021/ja01576a047
Organic Syntheses, Coll. Vol. 3, p. 475, 1955
Purification Methods
Crystallise indazole from water, sublime it in vacuo, then recrystallise it from pet ether (b 60-80o). The picrate crystallises from Et2O with m 136o. [Ainsworth Org Synth Coll Vol IV 536 1963, Beilstein 23 III/IV 1055, 23/6 V 156.]
