Phloroglucinol, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
Phloroglucinol (phlo) is a phenol derivative that shows a cytoprotective effect from oxidative damage by enhancing the activity of cellular catalase. It can also be used to prepare synthetic analogs of A-type proanthocyanidins (PACs) such as 2,8-dioxabicyclo nonane derivatives by reacting with the corresponding flavylium salts. Phlo can react with benzaldehyde derivatives to form phloroglucinol-based microporous polymeric organic frameworks (phlo-POF) with potential applications in ion exchange and gas adsorption. Phloroglucinol is an antispasmodic and a derivative of phenol.
