化學的特性
sodium pyrithione belongs to pyridine derivatives fungicide, appearance is yellow full light dumpling transparent liquid, melting point 250 ℃, slightly characteristic odor. Soluble in water and ethanol and other organic solvents, solubility (by mass fraction): water 53%, ethanol 19%, polyethylene glycol (PECG400) 12%. Best use pH range 7 to 10, mass fraction of 2% aqueous solution pH 8.0. Unstable to light, oxidizing agents and strong reducing agents. Non-ionic surfactants will deactivate it somewhat, and it can chelate with heavy metals.
使用
Sodium omadine is a bactericide for use in cooling fluids and short-term in-can preservation of vinyl acetate latex, paints, and synthetic-fiber
lubricants; preservative for cosmetic rinse-off products.
定義
Apparently exists in equilibrium with the -SH form. Forms chelates with iron, manganese, zinc, etc.
一般的な説明
2-Mercaptopyridine
N-oxide acts as labelling agent during indium-111 labelling of human platelets. It acts as bioactive ligand and forms palladium and platinum complexes, which were tested as potential antitrypanosomal agents.
安全性プロファイル
Poison by
intraperitoneal and intravenous routes.
Moderately toxic by ingestion, subcutaneous
and parenteral routes. Used in preservation
of cosmetics. When heated to
decomposition it emits very toxic fumes of
Na2O, NOx, and SOx. See also
MERCAPTANS.
純化方法
When recrystallised from water, it assayed as 98.7% based on AgNO3 titration [Krivis et al. Anal Chem 35 966 1963; see also Krivis et al. Anal Chem 48 1001 1976, and Barton & Crich J Chem Soc, Perkin Trans 1 1603, 1613 1986]. [Beilstein 21/7 V 151.]
