Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 68140-48-7 differently. You can refer to the following data:
1. Colourless Oil
2. TRASEOLIDE is a musk fragrance that is prepared from toluene and isobutanoyl chloride by a Friedel–Crafts reaction that yields p-tolyl isopropyl ketone; the ketone is reduced to the corresponding alcohol. Chlorination and treatment with 2-methyl-2-butene yield 1 (cipher)- isopropyl-2,3,3,5-tetramethylindane, which gives the title compound through a Friedel–Crafts reaction with acetyl chloride: It is used in perfume compositions for soaps and detergents.

Definition

ChEBI: An indane derivative in which the indane skeleton is substituted by geminal methyl groups at C-1, by single methyl groups at C-2 and C-6, by an isopropyl group at C-3 and by an acetyl group at C-6. It is a constituent of musk odorant.

Ketone precursors for organoleptic compounds

The invention discloses ketones of formula I: wherein, Y is an optionally substituted alkyl, cycloalkyl, or cycloalkylalkyl, wherein each alkyl group is straight or branched and each alkyl and cycloalkyl group is saturated or unsaturated; R1is hydrogen or a C1-6alkyl group that is substituted, saturated or unsaturated, straight or branched; A is a chromophoric substituted aromatic ring or ring system; n is an integer; and with the proviso that formula I is not 2-ethoxy-1-phenyl-ethanone. These compositions are useful for the delivery of organoleptic compounds, especially of flavors, fragrances, masking agents and antimicrobial compounds.
