2-Methyl butyric acid Chemical Properties,Usage,Production
Description
2-methyl butyric acid has a pungent, acrid odor which is similar to Roquefort cheese with an acrid taste. At low dilutions, it has a pleasant fruity taste. It can be prepared either by decarboxylation of methyl ethyl malonic acid or by the oxidation of fermentation amyl alcohol (fusel oil). It is used as a flavor ingredient for butter, cream, cheese flavor deployment. It also provides acyl moiety for the preparation of the respective flavor esters.

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
clear colorless to pale yellowish liquid
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. Slightly soluble in water, soluble in alcohol and oils. Also soluble in Propylene glycol and poorly soluble in Glycerin.
Occurrence
Occurring as the d-, l-, and dl-isomers; the racemic form has been reported found in angelica root oil and coffee; the d-isomer in the ester form has been identified in lavender oil. Also reported found in apple, apricot, berries, grapes, papaya, peach, guava, pineapple, potato, bell pepper, tomato, peppermint and spearmint oil, vinegar, wheat breads, cheeses, chicken, mutton, pork, hop oil, beer, cognac, rum, whiskies, cider, cocoa, coffee, tea, peanuts, passion fruit, trassi, mango, plum, tamarind, rice, corn oil, loquat, scallops, Chinese quince, maté, mammee apple and Roman chamomile oil, cranberry, grape brandy, oriental tobacco, and strawberry
Uses
2-Methylbutyric acid, can be used as food additive for butter, cream, cheese flavor deployment. It is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dyestuff. It is also used in the synthesis of 2-methylbutyric anhydride.
Uses
2-Methylbutyric acid was used in the synthesis of 2-methylbutyric anhydride, an acylating agent.
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.
Preparation
By decarboxylation of methyl ethyl malonic acid (with heat); also by oxidation of fermentation amyl alcohol (fusel oil).
Aroma threshold values
