Description

1,4-Dicyanonaphthalene is a high-purity, versatile naphthalene derivative widely utilized as a key synthetic intermediate in advanced organic chemistry. Its value lies in its rigid, planar aromatic structure and dual cyano functional groups, which enable precise molecular construction for complex target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science sectors, particularly for developing active ingredients and functional organic materials.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of novel active pharmaceutical ingredients (APIs), especially for compounds with naphthalene-based scaffolds.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators requiring specific aromatic architectures.
• Organic Electronic Materials: Acts as a precursor for electron-deficient units in the development of organic semiconductors, OLEDs, and photovoltaic materials.
• Ligand and Catalyst Development: Employed in the design and synthesis of specialized ligands for catalysis and metal-organic frameworks (MOFs).
• Dye and Pigment Intermediate: Provides the core structure for manufacturing high-performance dyes, pigments, and optical brighteners.
• Polymer Chemistry: Used as a monomer or cross-linking agent to introduce aromaticity and rigidity into specialty polymers and resins.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new organic reactions and material properties.

Quality Control

Our 1,4-Dicyanonaphthalene is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
