Hydrogen peroxide was first described in 1818 by Louis Jacques Thenard, who produced it by treating barium peroxide with nitric acid. Hydrogen Peroxide is the simplest peroxide (a compound with an oxygen-oxygen single bond) and in its pure form is a colorless liquid, slightly more viscous than water. It is a nonplanar molecule possessing (twisted) C2 symmetry. Hydrogen peroxide has a number of structural analogues of which hydrogen disulfide is perhaps the most closely related. It has the highest (theoretical) boiling point of all the analogues. Its melting point is also fairly high, being comparable to that of hydrazine, with only hydroxylamine crystallising significantly more readily. Hydrogen peroxide is also one of the two chief chemicals in the defense system of the bombardier beetle, reacting with hydroquinone to discourage predators. It is used in the production of certain organic peroxides, such as dibenzoyl peroxide, used in polymerisations and other chemical processes. It is used in certain waste water remediation processes. It oxidizes organic compounds as well as deodorizes sulfur-containing species. Hydrogen peroxide is generally recognized as safe (GRAS) as an antimicrobial agent, an oxidizing agent and for other purposes by the U.S. FDA. Hydrogen peroxide has been used, in sufficient concentrations, to disinfect inanimate objects. It has been used as a propellant in rocketry and as a hybrid rocket oxidiser. Hydrogen peroxide and benzoyl peroxide are sometimes used to treat acne. Hydrogen peroxide is also used in the oil and gas exploration industry to oxidize rock matrix in preparation for micro-fossil analysis. It is absorbed by skin upon contact and creates a local skin capillary embolism that appears as a temporary whitening of the skin.
