Gallic acid Usage And Synthesis

Chemical Properties	white powder
Usage	antineoplastic, astringent, antibacterial
General Description	Odorless white solid. Sinks in water.
Air & Water Reactions	Sparingly water soluble
Reactivity Profile	Phenols, such as Gallic acid, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.
Health Hazard	Inhalation of dust may irritate nose and throat. Contact with eyes or skin causes irritation.
Fire Hazard	Flash point data for Gallic acid are not available. Gallic acid is probably combustible.
