Product Introduction
Slightly special smell, strong astringency, exposure to light and deep color change in the air. Soluble in water, easily soluble in ethanol, acetone and glycerol, almost insoluble in ether, benzene, chloroform and petroleum ether. Slightly special smell and strong astringency.
Pale yellow amorphous powder or loose shiny scaly or spongy solid, which is mostly decomposed into pyrogallic acid and carbon dioxide at 210-215℃. 1g is dissolved in 0.35ml water and 1ml hot glycerin. It is odorless and flammable. When exposed to albumin, starch, gelatin, and many alkaloids and metal salts, they precipitate, and when exposed to iron salts, they also produce black or precipitate. Autoignition point 526.6℃; The median lethal dose (LD) (rabbit, oral) was 5.0g/kg.
Tannin is not a single compound, but its chemical composition is complex and can be roughly divided into two types:
(1) condensed tannin is flavanol, and the 2-position of flavanol in the molecule is combined with catechol or phloroglucinol through carbon-carbon bond.
② Hydrolyzable tannin, with ester bond in its molecule, is gallic acid ester of glucose. The latter is commonly used tannin. Tannin from Chinese gallnut contains about 12% glucose, and tannin from Turkish gallnut contains about 16.5% glucose.
Product Usage
Precipitation and gravimetric determination of beryllium, aluminum, gallium, indium, niobium, tantalum and zirconium. Comparative determination of copper, iron, vanadium, cerium and cobalt. Precipitators for proteins and alkaloids. External indicator for titration of lead with ammonium molybdate. Dye mordant.
Iron tannin complex was synthesized by reaction with metallic iron. Deproteins in the preparation of genome and plasmid DNA. As a reducing agent in the synthesis of metal nanoparticles.

| 설명 | This compound belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. |
