2-Methyl butyric acid Usage And Synthesis


Description

2-Methylbutyric acid has a pungent, acrid odor similar to Roquefort cheese with an acrid taste. At low dilutions, it has a pleasant fruity taste. May be prepared by decarboxylation of methyl ethyl malonic acid (with heat); also by oxidation of fermentation amyl alcohol (fusel oil).

Chemical Properties

2-Methylbutyric acid has a pungent, acrid odor similar to Roquefort cheese with an acrid taste. At low dilutions, it has a pleasant, fruity taste

Chemical Properties

clear colorless to pale yellowish liquid

Uses

Used in the synthesis of 2-methylbutyric anhydride

Definition

ChEBI: A methylbutyric acid comprising a butyric acid core carrying a 2-methyl substituent. Produced from amino acid leucine during nutrient starvation in bacteria.

Aroma threshold values

Detection: 10 to 60 ppb. Aroma characteristics at 1.0%: acidic sour, pungent, ripe fruit leather, lingon[1]berry, dirty cheesy, fermented pineapple fruity with a woody nuance

Taste threshold values

Taste characteristics at 10 ppm: dirty, acidic sour, ripe fruity, with a dairy buttery and cheesy nuance
