Organic acid presence of other substituents that affect the polarity of the compound. Simple organic acids like formic or acetic acids are used for oil and gas well stimulation treatments. These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid (HCl) or mixtures of HCl and hydrofluoric acid (HF). For this reason, organic acids are used at high temperatures or when long contact times between acid and pipe are needed. The conjugate bases of organic acids such as citrate and lactate are often used in biologically-compatible buffer solutions. Citric and oxalic acids are used as
Glutaconic acid can be used to make it: the "trans" form isomerizes under the reaction conditions. Glutaric, 3-hydroxyglutaric, and glutaconic acids are structurally related metabolites. In glutaric aciduria type 1, glutaconic acid accumulates, resulting in brain damage. Glutaconic acid "trans"-Glutaconic acid is an organic compound with formula HOCCH=CHCHCOH. This dicarboxylic acid exists as a colorless solid and is related to the saturated chemical glutaric acid, HOCC(CH)COH. Esters and salts of glutaconic acid are called glutaconates. The geometric isomer, "cis"-glutaconic acid, has a noticeably lower melting point (130–132 °C). It can be prepared by bromination of levulinic acid followed by treatment of the
