| Hazard Information | Back Directory | [Chemical Properties]
Wet crystalline aggregates or needle-like crystals (formed by ethanol or ether) evaporate when in contact with water vapor. These crystals have a melting point range of 58-61 ℃ and a flash point of 100 ℃. Indene compounds are commonly found in numerous natural products, exhibiting diverse physiological activities and serving as crucial intermediates in organic synthesis processes. | [Uses]
2-Indanone(615-13-4) undergoes TiCl4-Mg mediated coupling with CHBr3 to yield dibromomethyl carbinol. It reacts with 5,5-dimethyl-3-pyrazolidinone to yield 5,5-dimethyl-2-(1H-indenyl-2)-3-pyrazolidinone. On photolysis by 266-nm one-photon excitation yields o-xylylene. It was used as starting reagent in the synthesis of indene-fused porphyrins.
| [Application]
2-Indanone is mentioned mainly for the completion and illustration of the series in which dpila- and be{u-Hydrindone have been emphasized as having potential interest in the perfume industry. It is the author's impression that the two materials are not used in perfumes or flavors.
| [Definition]
ChEBI: 2-Indanone is an indanone with an oxo substituent at position 2. It is a metabolite of indane. It has a role as a xenobiotic metabolite. 2-Indanone is an intermediate for the preparation of aprindine hydrochloride and ceforanide. It is an important intermediate in organic synthesis. | [Preparation]
2-Indanone is prepared by using acetic acid as solvent, acetic anhydride as catalyst and through hydrogen peroxide oxidation into 1, 2-indenediol, which reacted with dilute sulfuric acid solution in order to obtain crude 2-indanone. Finally, vacuum sublimation to obtain 2-indanone with high-purity, the total yield is 89%. | [Synthesis Reference(s)]
