Cobalt(II) nitrate hexahydrate can be used as a:
- Starting material in the preparation of Co-based nanomaterials and Co complexes.
- Catalyst to synthesize 5-carboxanilide-dihydropyrimidinone derivatives via a three-component condensation reaction.
- Dopant to prepare LaCr1−xCoxO3 solid-solution ceramics for high temperature applications.
