Valeric acid

Valeric acid, or pentanoic acid, is a straight-chain carboxylic acid with five carbon atoms. It occurs naturally in some plants and is used in chemical synthesis.

Carboxylic acid: An organic compound containing a carboxyl group, –COOH, which can donate a proton. Valeric acid belongs to this family because it contains a terminal –COOH group.
Pentanoic acid: The IUPAC name for the straight-chain saturated carboxylic acid with five carbon atoms. It is the systematic name for valeric acid.
Valerate esters in perfumery: The use of pentanoate esters as fragrance ingredients, often for fruity or floral odor notes. Esterification converts valeric acid into odor-bearing compounds used in fragrance formulations.
Valerian: A genus of flowering plants that includes Valeriana officinalis, whose roots have a strong characteristic odor. The name valeric acid is associated historically with compounds obtained from valerian roots.
Pentanoate: The conjugate base and salts of pentanoic acid, formed when its carboxyl group loses a proton. Removing a proton from valeric acid produces the pentanoate ion.
Alkane: A saturated hydrocarbon containing only carbon–carbon and carbon–hydrogen single bonds. Valeric acid’s carbon chain is derived from a five-carbon alkane framework.
Ethyl valerate: The ethyl ester of pentanoic acid, used as a flavoring and fragrance compound. It is a common derivative made from valeric acid and ethanol.
Valeriana officinalis: A perennial plant commonly called common valerian, native to Europe and parts of Asia. Valeric acid’s traditional name reflects its early association with this plant.
Esterification: A reaction that forms an ester from an alcohol and a carboxylic acid, usually with water released. Valeric acid reacts with alcohols to produce pentanoate esters.
Carboxyl group: The functional group –COOH, consisting of a carbonyl group bonded to a hydroxyl group. This group gives valeric acid its defining acid chemistry.
