Gluconic acid, also known as 1,2,3,4,5-pentahydroxy pentane-1-carboxylic acid, is an organic acid with the formula C6H12O7. It is a white, odorless, crystalline powder that is naturally found in humans and other organisms and also in food products such as wine and honey.
Nitrilotriacetic acid, also known as NTA or N,N-bis(carboxymethyl)glycine, is a tricarboxylic acid with the formula C6H9NO6. It is a colorless solid that belongs to the family of aminopolycarboxylic acids and is one of the most important chelating agents, along with EDTA.
The trans, trans isomer of 2,4-hexadienoic acid, commonly known as sorbic acid, is a short-chain unsaturated fatty acid with the chemical formula C6H8O2. It is a naturally occurring organic acid that appears as colorless solid with a faint odor.
Methanoic acid, better known as formic acid, is the simplest carboxylic acid with the formula HCOOH. It is a colorless, corrosive liquid with a pungent odor that is completely miscible with water and many polar solvents but only partially miscible with hydrocarbons.
Malonic acid, also known as propanedioic acid or methanedicarboxylic acid, is a dicarboxylic acid with the chemical formula C3H4O4. It is a colorless, hygroscopic solid that sublimes in a vacuum. The ionized form of malonic acid, as well as its esters and salts, are known as malonates.
Propionic acid is a naturally occurring short-chain carboxylic acid with the formula CH3CH2COOH. It is a colorless liquid with a pungent odor, often described as resembling sweat or cheese.
Phthalic acid, also known as o-phthalic acid or 1,2-benzenedicarboxylic acid, is an aromatic dicarboxylic acid with the chemical formula C8H6O4. It is a white, crystalline solid that is not important industrially. It is formed as a byproduct in the manufacture of phthalic anhydride.
Methacrylic acid, also known as α-methylacrylic acid or 2-methylpropenoic acid, is an organic acid with the formula CH2=C(CH3)COOH. It is a colorless, moderately volatile, corrosive liquid with a strongly acrid odor.
Salicylic acid, also known as 2-hydroxybenzoic acid or o-hydroxybenzoic acid, is an aromatic compound with the formula C7H6O3. It is a colorless, odorless, crystalline solid that is found naturally in many plants, primarily as esters.
Tartaric acid, also known as acidum tartaricum, 2,3-dihydroxybutanedioic acid (IUPAC nomenclature), is a white crystalline organic acid found naturally in many fruits with the formula C4H6O6. The molecule possesses two asymmetric carbon centers with two carboxylic acid groups and a dialcohol in the same molecule, resulting in four stereoisomers.
Lactic acid, also known as 2-hydroxypropionic acid, is a natural organic acid with the molecular formula CH3CH(OH)COOH. Pure lactic acid is a white, crystalline solid with a low melting point that is found in many biological systems, including the human body.
Crotonic acid is the trans-isomer of 2-butenoic acid. It is a short-chain, unsaturated carboxylic acid with the chemical formula CH3CH=CHCOOH. The cis isomer of 2-butenoic acid is known as isocrotonic acid.
