A dicarboxylic acid is an organic compound containing two carboxyl functional groups (−COOH). The general molecular formula for dicarboxylic acids can be written as HO 2 C−R−CO 2 H, where R can be aliphatic or aromatic. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic oxylic acids are also used in the preparation of.

A possible reaction scheme includes the successive steps of alkylation of thiophene with carbon tetrachloride, leading to 2-trichloromethylthiophene, and alcoholysis of the product giving the Cited by: 6.
A long-standing puzzle in the synthesis of the key metabolic cofactor, biotin, was the source of pimelate moiety that contributes carbons 1 through 7 of biotin ().Pimelic acid (heptanedioic acid) has long been known to be a biotin precursor because it bypassed the biotin requirement of Corynebacterium diphtheriae [1, 2] and stimulated biotin synthesis in certain bacteria and by: A.

furfural (HMF) which is a key precursor for the synthesis of derivates with applications within pharmaceutical and polymer industry . Recently, Au supported catalysts have been found to be very active for the 5-hydroxymethylfurfural (HMF) oxidation to 2,5-furandicarboxylic acid (FDCA), a possible removable substitute of terephthalate acid.
Synthesis of Carboxylic Acids. There are many possible synthetic pathways that yield carboxylic acids. Some of these are further discussed below. Alcohols and aldehydes may be oxidized into carboxylic acids. Alkenes may be converted into carboxylic acid through oxidative cleavage of the double bond with neutral or acid permanganate, for instance.
Recently, polyester plasticizers are paid more attention because they are characterized by low toxicity, good compatibility, low migration . A series of recent publication reported the synthesis and application of plasticizers such as oleic acid polyester, citric acid-based polyester, castor oil based polyester.A tricarboxylic acid is an organic carboxylic acid whose chemical structure contains three carboxyl functional groups (-COOH).
