Description

4,5-Diaminophthalonitrile is a high-purity, versatile aromatic diamine derivative with a nitrile functionality. This compound is a critical advanced intermediate for the synthesis of complex organic molecules, particularly phthalocyanines and other functional dyes and pigments. It is essential for R&D and production in the pharmaceutical, agrochemical, and specialty materials sectors, where precise molecular construction is required.

Application

• Phthalocyanine Precursor: A key building block for the synthesis of asymmetrical and functionalized phthalocyanines used in dyes, pigments, and advanced materials.
• Pharmaceutical Intermediate: Employed in the research and development of active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used in creating novel herbicides, fungicides, and plant growth regulators.
• Organic Electronics: Serves as a precursor for organic semiconductors, conductive polymers, and non-linear optical (NLO) materials.
• Coordination Chemistry: Acts as a versatile ligand for constructing metal-organic frameworks (MOFs) and coordination complexes with catalytic properties.
• Polymer Modification: Used to introduce amino and nitrile functional groups into polymer backbones to enhance properties like adhesion and thermal stability.

Quality Control

Our 4,5-Diaminophthalonitrile is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong oxidizing agents.
