Finds a little use in flavor compositions for imitation Grape, in Vanilla flavors, Creamsoda compositions, etc.

Chemical Properties

2,4-Dimethylacetophenone has a sweet-floral, woody odor, rather pungent in the pure state, but almost Mimosa-like in extreme dilution or in proper composition with other perfume chemicals.

Chemical Properties

CLEAR COLORLESS TO VERY SLIGHTLY YELLOW LIQUID

Occurrence

Reported found in cinnamon bark, wine, tea, watercress and dried bonito.

Uses

2',4'-DIMETHYLACETOPHENONE (cas# 89-74-7) is a useful research chemical. This compound can be used to detect aldosterone aroma in tobacco compounds using Gas Chromatography. It can also be used for protecting food products.

Preparation

By condensation of acetylchloride and m-xylene in the presence of aluminum chloride or in the presence of ferric chloride

Aroma threshold values
