Description

General description

Catechin hydrate is a polyphenolic flavonoid that exhibits antioxidant properties. It is commonly found in green tea, grape seeds, and bark of few trees like acacia and mahogany.

Application

(+)-Catechin hydrate can be used:

• As an inhibitor of steel corrosion in hydrochloric acid solution.
• As a model compound in the study of antimicrobial activities of flavonoids on Escherichia coli.
• As a starting material for the synthesis of catechin glucosides of biological importance.

Caution

loses water of hydration during storage
