Description and Uses

Cobalt(II) chloride hexahydrate (CoCl2·6H2O) has been found to be an efficient catalyst for the one-pot synthesis of biscoumarin derivatives through a combination of aromatic aldehydes and 4-hydroxycoumarin in aqueous media at 70°C. Cobalt chloride hexahydrate can be used as an inducer of HIF-1 production used to study apoptotic effects in HepG2 cells. It is also used as APHA color standard.
