4-Methyloctanoic acid Chemical Properties,Uses,Production
Description
4-Methyloctanoic acid, also known as Hircinoic Acid, presents as a colorless to pale-yellow oil. It is slightly soluble in chloroform, DMSO and ethyl acetate. Store in a tightly closed container in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. This substance is stable under recommended storage conditions. 4-Methyloctanoic Acid is incompatible with strong oxidizing agents as well as strong bases. This chemical causes severe skin burns and eye damage.

4-Methyloctanoic acid has a fatty, musty, plastic odor. This compound is also reported to have a goat, costus, mutton odor
Physical properties
4-Methyloctanoic acid is one of the acids mainly responsible for the so-called "soo" odour of mutton. The analogue 4-Ethyloctanoic acid (found in Virginia tobacco and Costus root oil) also has a related goaty odor; this analog has the lowest threshold of all the fatty acids at 1.8 ppb. 4-Methyloctanoic acid is used in flavours for cheese, meat, tobacco and (possibly) fish. Normal use levels in finished consumer product: up to 3 ppm.
Occurrence
Reported found in cooked mutton fat, raw and cooked mutton, lamb, and blue, cheddar, parmesan, provolone and romano cheeses

Definition
ChEBI: 4-methyl-octanoic acid is a medium-chain fatty acid.
Aroma threshold values
Aroma characteristics at 1.0% in PG: waxy, fatty, meaty, reheated beef-like with a slightly lactonic cheesy nuance
Taste threshold values
Taste characteristics at 10 ppm: fatty, waxy, creamy and lactonic with a satiating fatty mouthfeel and metallic nuances.
