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 pyrithione (or pyrithione zinc) is a coordination complex of zinc. It has fungistatic (inhibiting the division of fungal cells) and bacteriostatic (inhibiting bacterial cell division) properties and is used in the treatment of seborrhoeic dermatitis [ 2 ] and dandruff .

Example of a reduction–oxidation reaction between sodium and chlorine, with the OIL RIG mnemonic [1] Tetracyanoquinodimethane is an organic electron-acceptor. Electron acceptors participate in electron-transfer reactions. In this context, the oxidizing agent is called an electron acceptor and the reducing agent is called an electron donor.
These types of reactions are rare because the allergenic component of pyrethrin in semi-synthetic pyrethroids has been removed. [31] The metabolite compounds of pyrethrin are less toxic to mammals than their originators, and compounds are either broken down in the liver or gastrointestinal tract , or excreted through feces; no evidence of ...

The following list includes the metallic elements of the first six periods. It is mostly based on tables provided by NIST. [9] [10] However, not all sources give the same values: there are some differences between the precise values given by NIST and the CRC Handbook of Chemistry and Physics. In the first six periods this does not make a ...
