Diacetone Alcohol (DAA)
CAS Number: 123-42-2
Diacetone alcohol (DAA, ≥99.0%) is a high-boiling bifunctional solvent combining both hydroxyl and ketone groups, giving it a unique dual solvency for polar resins, cellulose derivatives, and waterborne systems. It is used in high-boiling solvent blends for coatings, cleaners, and as a chemical intermediate for mesityl oxide.
