Potassium phthalimide

Potassium phthalimide (CAS 1074-82-4), also known as potassium phthalimidate, is a potassium salt of phthalimide; a synthetic building block in organic chemistry manufacturing.

Where is Potassium phthalimide used?

• Organic synthesis: nucleophilic nitrogen source in the Gabriel synthesis for primary amines and amino acid derivatives
• Pharmaceutical manufacturing: key intermediate for active pharmaceutical ingredients, including amino acids, antifungals and other nitrogen-containing compounds
• Textile and leather processing: phthalimide-derived compounds impart flame retardancy and durable finishing
• Polymer and plastics production: synthesis of flame-retardant additives and specialty monomers for engineering resins
• Personal care: downstream derivatives serve in preservation and conditioning actives.

Commercial specifications

• Purity specifications typically from 98% upward
• Packaging: multi-kilogram bags and drum quantities
