Pimelic

Pimelic is a term that can refer to several related chemical compounds, all of which are dicarboxylic acids. The most common compound referred to as pimelic is heptanedioic acid, a seven-carbon saturated dicarboxylic acid with the chemical formula C7H12O4. It is a white crystalline solid that is soluble in water and alcohol. Heptanedioic acid is a member of the aliphatic dicarboxylic acid family.

Other less common compounds can also be referred to as pimelic, typically involving derivatives of heptanedioic acid or related structures. However, without further context, "pimelic" most often implies heptanedioic acid itself.

Heptanedioic acid can be synthesized through various chemical routes, including the oxidation of cycloheptanone or pimelaldehyde. It occurs naturally in some plants and is a metabolic intermediate in certain biological pathways. Industrially, it finds applications in the synthesis of polymers, plasticizers, and fragrances. It can also be used as a precursor in the production of certain pharmaceuticals and specialty chemicals. Its presence in biological systems is generally as a minor component or intermediate rather than a primary constituent.
