Chemical Properties

1-Phenyl-1,2-propanedione has a pungent, plastic odor.

Chemical Properties

clear yellow liquid

Occurrence

Reported found as a constituent in coffee, baked potato and butter.

Uses

Pyruvophenone was used in the synthesis of opioid receptor agonists for gastrointestinal disorders. The enantioselective hydrogenation of Pyruvophenone over Pt colloids was also studied.

Definition

ChEBI: An alpha-diketone that consists of 1-phenylpropane bearing keto substituents at positions 1 and 2. It is found in coffee.

Aroma threshold values

Aroma characteristics at 1.0%: creamy, buttery, fatty, slightly vanillalike, slightly walnut nutty, almond and marzipanlike with a woody styraxlike nuance, and having a slightly sour yeasty and fermented nuance.

Taste threshold values

Taste characteristics at 5 ppm: cultured creamy, dairylike and slightly astringent with a slight spicy caraway/ cumin nuance.

Synthesis Reference(s)
