It converts thiols selectively to disulfides, secondary alcohols to ketones, sulfides to sulfoxides and sulfones, nitriles to amides, and N-heterocycles to amine oxides. Hydroxybenzaldehydes are converted to dihydroxybenzenes (Dakin reaction) and give, under suitable conditions, the corresponding benzoic acids. It oxidizes ketones to esters, in particular cyclic ketones, such as substituted cyclohexanones or cyclobutanones to give lactones (Baeyer-Villiger oxidation). The epoxidation of various alkenes in the presence of benzonitrile yields oxiranes in yields of 79 to 96%. The oxygen atom transferred to the alkene originates from the peroxoimide acid formed intermediately from benzonitrile. The resulting imidic acid tautomerizes to the benzamide. Safety
The compound acts as a strong oxidizing agent and can cause skin irritation and severe eye damage. See also

Botulinum toxin, often shortened to BoNT, is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. The toxin causes the disease botulism. The toxin is also used commercially for medical and cosmetic purposes. The seven main types of botulinum toxin are named types A to G (A, B, C1, C2, D, E, F and G). New types are occasionally found. Types A and B are capable of causing disease in humans, and are also used commercially and medically. Types C–G are less common; types E and F can cause disease in humans, while the other types cause disease in other animals. Botulinum toxin types A and B are used in medicine to treat various muscle spasms. Botulinum toxins are among the most potent toxins known. Intoxication can occur naturally as a result of either wound or intestinal infection or by ingesting formed toxin in food. The estimated human lethal dose of type A toxin is 1.3–2.1 ng/kg intravenously or intramuscularly, 10–13 ng/kg when inhaled, or 1000 ng/kg when taken by mouth. Commercial forms are marketed under the brand names Botox (onabotulinumtoxinA), Dysport/Azzalure (abobotulinumtoxinA), Xeomin/Bocouture (incobotulinumtoxinA), and Jeuveau (prabotulinumtoxinA). Medical uses
Botulinum toxin is used to treat a number of therapeutic indications, many of which are not part of the approved drug label.
