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.
Cyanuric acid, also known as 1,3,5-triazine-2,4,6(1H,3H,5H)-trione, is an odorless white crystalline solid with a molecular formula of C3H3N3O3. It is a cyclic trimer that interconverts between several structures via lactam-lactim tautomerism.
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.
Phthalonitrile, also known as 1,2-dicyanobenzene or 1,2-benzenedicarbonitrile, is an organic compound with the formula C8H4N2. It is a crystalline powder with a faint grayish yellow color and a slight aromatic odor, similar to benzonitrile.
Phthalimide, also known as 1,3-dioxoisoindoline, is an organic compound with the chemical formula C8H5O2N. It is a white solid that is slightly soluble in water and soluble in basic solutions.
Phthalic anhydride [85-44-9], also known as isobenzofuran-1,3-dione, is an organic compound with the formula C6H4(CO)2O. It is a colorless to white, solid in the form of needles with a mild, distinctive odor that is formed by the dehydration of phthalic acid.
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.
