Chemical Structure

Basic Info
5-Methyloctanoic Acid (CAS No. The molecular formula is C9H18O2, and the molecular mass is 158.24g/mol. The methyl group (CH3) is introduced on the fourth carbon of the octanoic (C8 fatty) acid to create an asymmetrical carbon center. This gives the compound a unique chirality. It is an oily, colorless liquid that is slightly soluble with water and readily soluble with organic solvents like ethanol and ether. The compound has a characteristic smell of goat fat and sweat acid. Its threshold (ppb) is very low, so it must be used with extreme caution in perfumery.

Product Packaging
1. Food flavoring and fragrance industry
The 4-Methyloctanoic Acid, with its strong scent of goat fat, sweat acid and fermented chees, is used primarily as a flavor modifier for food, especially:
Trace additions can be used to enhance the “wild” taste of fermented dairy foods such as butter and cheese (especially goat’s cheese), and simulate the complex aromas of mature cheese.
Meat flavors are used to enhance the meat aroma and authenticity by blending animal fats like beef and mutton.
Tropical fruit flavors can accelerate the ripening of tropical fruits like pineapple and mango, even at very low concentrations.
It is important to dilute it (normally to a concentration below 0.1%), and to use other fatty acid (such as caproic and butyric acids) in order to balance its flavor.
2. Everyday chemicals and functional flavors
A small amount of this substance is added to leather-based and animal-based perfumes (such as castoreum, musk or castoreum), in order to enhance the original roughness.
Masking agent: 4-methyloctanoic acids can be added to detergents or deodorants in order to mask odors, and increase the feeling of cleanliness.
3. Agriculture and insect pheromones
Pest attractant: It is used to trap fruit flies or interfere with their mating in order to reduce pesticide use.
Research in animal husbandry: Its smell is similar to that of animals and can be used as a tool for research on livestock behavior, parasite control or research into livestock management.
4. Chemical synthesis and medicine
Chiral intermediate: As a branched fat acid, 4-methyloctanoic can be used for the synthesizing of drugs (such anti-inflammatory drugs), or optically active modules in liquid crystal materials.
Research on microbiome: Certain skin flora, such as Staphylococcus, will produce short-chained branched fatty acid through metabolism. This can be used to analyze the mechanism behind body odor.
5. Industrial use
Rubber/plastic additives are used in trace amounts to mask the sulfur odor when polymer materials are processed.
Surfactant derivatives : 4-Methyloctanoic Acid is esterified into compounds with special wetting characteristics.
