Potassium phthalimide

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

It serves as a nucleophilic nitrogen source in the Gabriel synthesis, enabling the production of primary amines and amino acid derivatives at industrial scale for various chemical sectors.

In pharmaceutical manufacturing, it functions as a key intermediate for synthesizing active pharmaceutical ingredients, including amino acids, antifungals, and other nitrogen-containing compounds.

Textile and leather processors use phthalimide-derived compounds to impart flame retardancy and durable finishing properties to treated substrates during the manufacturing and finishing stages.

In polymer and plastics production, it contributes to the synthesis of flame-retardant additives and specialty monomers incorporated into engineering resins for high-performance applications.

Personal care formulators access phthalimide chemistry through downstream derivatives used in preservation and conditioning actives to ensure product stability and efficacy in consumer goods.

Potassium phthalimide is supplied as a white to off-white crystalline powder. It is available in technical and pharmaceutical-intermediate grades, with purity specifications typically ranging from 98% upward.

Packaging options generally include multi-kilogram bags and drum quantities suited to both laboratory-scale procurement and bulk industrial orders to meet diverse supply chain requirements.
