Butyric acid (/ ˈ b j uː t ɪ r ɪ k /; from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH 2 COOH. It is an oily, colorless liquid with an unpleasant odor.
3-Mercapto-3-methylbutan-1-ol, also known as MMB, is a common odorant found in food and cat urine. The aromas ascribed to MMB include catty, [3] roasty, broth-like, meaty, and savory, [4] or similar to cooked leeks. [5] MMB is an organosulfur compound with the formula C 5 H 12 OS.
A cat pheromone is a chemical molecule, or compound, that is used by cats and other felids for communication. [1] These pheromones are produced and detected specifically by the body systems of cats and evoke certain behavioural responses. [1] [2] Cat pheromones are commonly released through the action of scent rubbing. [2]
A precursor for mercaptan is 3-mercapto-3-methylbutanol (MMB). MMB is a chemical which gives a strong odor to cat urine. This smell is likely used for communicating amongst cats as well as scaring away predators and rivals. That is, the smell can mark their territory amongst other male cats and attract a female mate.

Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apples or pineapples. [2] At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer.
Body Odor and Disease. In mammals, body odor can also be used as a symptom of disease. One's body odor is completely unique to themselves, similar to a fingerprint, and can change due to sexual life, genetics, age and diet. Body odor, however, can be used as an indication for disease.
Isovaleric acid, also known as 3-methylbutanoic acid or β-methylbutyric acid, is a branched-chain alkyl carboxylic acid with the chemical formula (CH 3) 2 CHCH 2 CO 2 H. It is classified as a short-chain fatty acid. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. The compound occurs naturally and can be found in ...
It is a colorless liquid with a unpleasant odor. Butyryl chloride is soluble in organic solvents, but it reacts readily with water and alcohols. It is usually produced by chlorination of butyric acid. [1]
