Benzyl alcohol (-hydroxytoluene) is an aromatic alcohol used as an antimicrobial preservative at concentrations ranging from 0.9% to 2.0% in many multidose medication vials and parenteral solutions. Unlike most flavoprotein oxidases, AAO does not thermodynamically stabilize a flavin semiquinone (CH3)2CHCH2OH b. Its polarity, low toxicity, and low vapour pressure make it a useful solvent. Molecular formula of benzoic acid = C 7 H 6 O 2. Acetaminophen, propofol, carprofen, and aspirin are eliminated much more slowly in cats, and are all metabolized by conjugation. The hydroxyl radical (OH ) from hydrogen peroxide reacts with the benzyl radical to form benzyl alcohol which is further oxidized into benzaldehyde by the excess of hydroxyl radicals. From trends in the concentration profiles and integrated production of each product, it was determined that there are two primary reaction paths: A) an alkoxy pathway leading to toluene, benzaldehyde, and benzyl ether, and B) a carbonyloxyl pathway ("neutral carboxylate") leading to benzoic acid, benzene, and benzyl benzoate.
