Chemical formula. C 10 H 8 N 2 O 2 S 2 Zn Molar mass: 317.70 g/mol Appearance colourless solid ... Zinc pyrithione (or pyrithione zinc) is a coordination complex of zinc.
Pyrithione is the common name of an organosulfur compound with molecular formula C 5 H 5 NOS, 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.

Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
Zinc pyrithione is used in antifouling paints. [148] Zinc powder is sometimes used as a propellant in model rockets. [149] When a compressed mixture of 70% zinc and 30% sulfur powder is ignited there is a violent chemical reaction. [149] This produces zinc sulfide, together with large amounts of hot gas, heat, and light. [149]
Organozinc chemistry. Organozinc chemistry is the study of the physical properties, synthesis, and reactions of organozinc compounds, which are organometallic compounds that contain carbon (C) to zinc (Zn) chemical bonds. [1][2][3][4] Organozinc compounds were among the first organometallic compounds made. They are less reactive than many other ...
Pyrethrin. The pyrethrins are a class of organic compounds normally derived from Chrysanthemum cinerariifolium that have potent insecticidal activity by targeting the nervous systems of insects. Pyrethrin naturally occurs in chrysanthemum flowers and is often considered an organic insecticide when it is not combined with piperonyl butoxide or ...
Spinel group. The spinels are any of a class of minerals of general formulation AB. 2X. 4 which crystallise in the cubic (isometric) crystal system, with the X anions (typically chalcogens, like oxygen and sulfur) arranged in a cubic close-packed lattice and the cations A and B occupying some or all of the octahedral and tetrahedral sites in ...
Piroctone olamine is the ethanolamine salt of the hydroxamic acid derivative piroctone was first synthesized in 1979 by Schwarzkopf-Henkel (Germany). It is often used in anti- dandruff shampoo as a replacement for the commonly used compound zinc pyrithione which was banned in the EU in 2021 because of concerns for environmental toxicity.
