Potassium phthalimide

Potassium phthalimide (CAS 1074-82-4, EC 214-046-6), also known as phthalimidopotassium or N-potassiophthalimide, is the potassium salt of phthalimide, supplied as a crystalline powder. It carries no assigned E-code and is classified under HS code 29251995 within the salts and minerals category.

In pharmaceutical synthesis, potassium phthalimide serves as a nitrogen source in the Gabriel synthesis, enabling the production of primary amines from alkyl halides under controlled conditions. In plastics and polymer formulations, it functions as a flame retardant by releasing nitrogen-based species that interrupt combustion. Personal care formulators also incorporate it as an antimicrobial and skin-conditioning agent.

The material is available in technical and pharmaceutical-grade forms, subject to REACH registration requirements for EU supply. Procurement quantities are offered in standard industrial packaging, with documentation available to support compliance workflows. Buyers should confirm grade specifications against applicable pharmacopoeial or internal quality standards before ordering.
