Methyl pentanoate, commonly known as methyl valerate, is the methyl ester of pentanoic acid (valeric acid) with a fruity odor. Methyl pentanoate is commonly used in fragrances, beauty care, soap, laundry detergents at levels of 0.1–1%. In a very pure form (greater than 99.5%) it is used as a plasticizer in the manufacture of plastics.
The valerate, or pentanoate, ion is C 4 H 9 COO −, the conjugate base of valeric acid. It is the form found in biological systems at physiological pH . A valerate, or pentanoate, compound is a carboxylate salt or ester of valeric acid.
In Poland, Bulgaria, Romania and the former Soviet Union states including Russia, menthyl isovalerate mixed with roughly 25% menthol is sold as an anxiolytic under various trade names including Extravalerianic, Validol, Valofin, and Menthoval.
The oxidation products derived from methyl are hydroxymethyl group −CH 2 OH, formyl group −CHO, and carboxyl group −COOH. For example, permanganate often converts a methyl group to a carboxyl (−COOH) group, e.g. the conversion of toluene to benzoic acid. Ultimately oxidation of methyl groups gives protons and carbon dioxide, as seen in ...
Estradiol valerate was first described in 1940 and was introduced for medical use in 1954. [19] [20] [21] Along with estradiol cypionate, it is one of the most widely used esters of estradiol. [22] Estradiol valerate is used in the United States, Canada, Europe, and throughout much of the rest of the world. [23] [24] It is available as a ...
Pentyl pentanoate (C 4 H 9 COOC 5 H 11) is an ester used in dilute solution to replicate the scent or flavour of apple, and sometimes pineapple. [1] It is referred to as pentyl valerate or amyl pentanoate using classical nomenclature. it can be used for a variety of chemical uses, such as in the production of flavoured products, like sweets.

An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
