In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO 2 H, sometimes as R−C(O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups ...
The first reported synthesis of the pyrazole acid was in 1993, by chemists at Monsanto. [7]The ethyl ester of difluoroacetoacetic acid is treated with triethyl orthoformate in the presence of acetic anhydride [8] and then with methyl hydrazine, which forms mainly the required pyrazole ring, in addition to its isomer with the methyl group on the alternative nitrogen atom.
Quinmerac is used as a herbicide to control various pests, such as chickweed, that affect cereals, rape, and sugar beets. [4] In a 2015 survey of herbicides, quinmerac was rated as having the sixth-highest market share out of the most popular herbicides used with sugar beet crops with a 7.6% share.
Trifluoroacetic acid is a widely employed acid, used for example in the synthesis of peptides.Its esters are useful in analytical chemistry. Longer-chain perfluoroalkyl carboxylic acids, e.g. with five to nine carbons, are useful fluorosurfactants and emulsifiers used in the production of polytetrafluoroethylene (Teflon) and related fluoropolymers.

Haloacetic acids or HAAs are carboxylic acids in which one or more halogen atoms take the place of hydrogen atoms in the methyl group of acetic acid. In a monohaloacetic acid, a single halogen replaces a hydrogen atom: for example, in bromoacetic acid .
Omega−3-carboxylic acids are used in addition to changes in diet to reduce triglyceride levels in adults with severe (≥ 500 mg/dL) hypertriglyceridemia. [6]Intake of large doses (2.0 to 4.0 g/day) of long-chain omega−3 fatty acids as prescription drugs or dietary supplements are generally required to achieve significant (> 15%) lowering of triglycerides, and at those doses the effects ...
Ferrocenecarboxylic acid is the organoiron compound with the formula (C 5 H 5)Fe(C 5 H 4 CO 2 H). It is the simplest carboxylic acid derivative of ferrocene . It can be prepared in two steps from ferrocene by acylation with a 2-chlorobenzoyl chloride followed by hydrolysis.
