Description

General description

Cobalt (II) nitrate hexahydrate is a simple, inexpensive and readily available cobalt precursor to develop cobalt-based catalyst for specific organic reactions.

Application

Cobalt (II) nitrate hexahydrate is used as a catalyst:

• In the synthesis of 5-carboxanilide-dihydropyrimidinone derivatives from acetoacetanilide, aldehyde, and urea/thiourea by condensation reaction.
• In the multi-component synthesis of 2-amino-3- cyanopyridine and pyranopyrazole derivatives.
• Cobalt (II) nitrate hexahydrate can also be used:,In the preparation of nano-Co₃O₄ by direct thermal decomposition, that are used in electrochemical water splitting and electrochemical sensors.
