Description
ACS reagent, ≥98%
Linear Formula: Al(NO3)3 · 9H2O
General description
Aluminum nitrate nonahydrate is an aluminum salt that can be prepared by dissolving aluminum or aluminum hydroxide in dilute nitric acid. It is used in the preparation of insulating papers, transformer core laminates, and cathode-ray tube heating elements.
Application
Aluminum nitrate nonahydrate can be used as a catalyst to synthesize:
- β-Amino carbonyl compounds via one-pot Mannich reaction.
- Bis(indolyl)methanes via electrophilic substitution reaction of indoles with aromatic aldehydes.
- 3,4-Dihydropyrimidinones via solvent-free Biginelli reaction.
