Pyrogallic Acid is an organic compound that has the following properties and uses:
Properties of Pyrogallic Acid:
An odorless white to gray solid with a bitter taste.
Soluble in water, ethanol, ether and other organic solutions, slightly soluble in benzene, chloroform, carbon disulfide.
It sublimates when heated and turns pale gray when exposed to air. When the aqueous solution of Pyrogallic Acid is exposed to air, the color gradually darkens, while the caustic solution changes color faster.
Application of Pyrogallic Acid:
Chemical Synthesis and Industrial Applications:
Used in the preparation of metal colloidal solutions, leather coloring, fur and hair dyeing and etching.
In industry, it is also used as a developer for motion picture film, infrared photographic thermosensitive agent, styrene and polystyrene inhibitor.
Pharmaceutical and dye intermediates:
Mainly used as an intermediate in medicine and as an important raw material in other drug synthesis. Its characteristic is that it can participate in a variety of chemical reactions, so as to prepare the required drug molecules.
In dye manufacturing, as an intermediate, participates in the synthesis of acid dyes, direct dyes and disperse dyes. This compound can help form a variety of dye molecules to meet different dyeing needs through its specific chemical structure.
Cosmetics:
Powder: In cosmetics, it is used as an ingredient to increase the fineness and adhesion of cosmetics, making products more comfortable to use.
Hair conditioner: This ingredient can help protect hair from environmental damage while providing shine and softness.
Hair dye: it is also used in hair dyes and can help provide long-lasting color retention and increase the adhesion and vitality of dyed hair.
Metal detection:
Deoxidizing agent in chemical analysis: Pyrogallic Acid is an indispensable deoxidizing analytical reagent in nitrogen fertilizer, coking, smelting, petrochemical and other industries.
Metal ion reduction: As a strong reducing agent in the analysis of gold, silver, mercury salts, etc., by reacting with metal ions to change the oxidation state of metal ions, so as to detect the content of metal ions.
Health and Safety Aspects of Pyrogallic Acid:
Direct exposure to Pyrogallic Acid can irritate the skin and eyes. Inhalation or ingestion may lead to more severe health issues, including toxicity affecting the central nervous system and kidneys.
Safe Handling and Storage Guidelines of Pyrogallic Acid:
