| | 3,4-Hexanedione Usage And Synthesis |
| Description | 3,4-Hexanedione has a pungent, unpleasant odor reminiscent of
butter and a taste similar to that of diacetyl. May be prepared
synthetically by condensation of ethyl propionate in the presence
of sodium metal, followed by oxidation of the resulting propionin
with copper acetate or ferric chloride. | | Chemical Properties | clear yellow liquid | | Chemical Properties | 3,4-Hexanedione has an aromatic, toasty, burnt, buttery, nutty, caramel-eggy, pungent odor. | | Occurrence | Reported found in cauliflower, coffee | | Preparation | By condensation of ethyl propionate in the presence of sodium metal, followed by oxidation of the resulting propionin
with copper acetate or ferric chloride. | | Definition | ChEBI: 3,4-Hexanedione is an alpha-diketone. | | Aroma threshold values | Aroma characteristics at 1.0%: sweet buttery, creamy, slightly cooked caramel and burnt sugary reminiscent of ghee and eggy vanillas. | | Taste threshold values | Taste characteristics at 5 ppm: sweet buttery, creamy, pound cake and egg caramel-like with vanilla nuances. | | General Description | The dermal irritation and sensitization potential of 3,4-hexanedione (used as constituents of synthetic flavoring agent) was studied using a murine model. The 3,4-hexanedione derivatives inhibited oxoglutarate transport. | | Biochem/physiol Actions | Odor at 1.0% |
