Description

1,4,5,8-Naphthalenetetracarboxylic Dianhydride is a high-purity, polycyclic aromatic organic compound that serves as a critical building block in advanced materials synthesis. Its rigid, planar structure and multiple reactive anhydride groups make it an essential precursor for creating high-performance polymers and dyes. This chemical is primarily sought by manufacturers in the electronics, specialty plastics, and advanced pigment industries for developing materials with exceptional thermal stability and optical properties.

Application

• Polyimide Precursor: A key monomer for synthesizing high-temperature, high-performance polyimide resins and films used in flexible printed circuits (FPCs) and aerospace components.
• Perylene-Based Pigments & Dyes: Core intermediate for manufacturing perylene tetracarboxylic diimide (PTCDI) derivatives, which are vital for high-grade organic pigments, vat dyes, and photoconductive materials.
• Organic Semiconductor Materials: Used in the development of n-type organic semiconductors for organic field-effect transistors (OFETs) and photovoltaic cells due to its electron-accepting properties.
• Liquid Crystal Polymers (LCPs): Incorporated as a monomer to enhance the thermal and mechanical properties of engineering plastics for electronic connectors and automotive parts.
• Fluorescent Whitening Agents: Serves as a starting material for certain classes of optical brighteners used in paper and textile industries.
• Research & Development: Employed in academic and industrial R&D for exploring novel organic electronic materials, metal-organic frameworks (MOFs), and covalent organic frameworks (COFs).

Quality Control

Our 1,4,5,8-Naphthalenetetracarboxylic Dianhydride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet the stringent requirements of advanced material applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent hydrolysis of the anhydride groups. Keep away from strong bases and amines.
