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)]

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.] |
