Chemical compound
Pyrithione is the common name of an organosulfur compound with molecular formula C 5H 5NOS, chosen as an abbreviation of pyridinethione, and found in the Persian shallot.[4] It exists as a pair of tautomers, the major form being the thione 1-hydroxy-2(1H)-pyridinethione and the minor form being the thiol 2-mercaptopyridine N-oxide; it crystallises in the thione form.[5] It is usually prepared from either 2-bromopyridine,[1] 2-chloropyridine,[6][7] or 2-chloropyridine N-oxide,[8] and is commercially available as both the neutral compound and its sodium salt.[1] It is used to prepare zinc pyrithione,[9][10] which is used primarily to treat dandruff and seborrhoeic dermatitis in medicated shampoos,[11][12] though is also an anti-fouling agent in paints.[13]
