Description

1,1,2,2,9,9,10,10-Octafluoro[2.2]Paracyclophane is a highly fluorinated, cage-like organic compound belonging to the paracyclophane family. This unique structure makes it a critical precursor for advanced materials, particularly in the electronics and semiconductor industries. It is primarily sought after by manufacturers and R&D facilities specializing in the production of parylene-type polymers and other high-performance fluorinated coatings.

Application

• Parylene Polymer Precursor: Serves as the key monomer for the chemical vapor deposition (CVD) synthesis of fluorinated parylene (Parylene AF-4) coatings.
• Semiconductor Manufacturing: Used to create ultra-thin, conformal, and chemically inert dielectric and protective layers on sensitive electronic components and micro-electromechanical systems (MEMS).
• Advanced Electronics: Provides moisture, chemical, and electrical insulation for high-reliability applications in aerospace, military, and medical device circuitry.
• Optical Coatings: Enables the production of coatings with specific refractive indices and durability for optical fibers and lenses.
• Nanotechnology & Surface Modification: Acts as a building block for creating specialized fluorinated surfaces with low surface energy and high thermal stability.
• Research & Development: Utilized in academic and industrial labs for developing novel fluoropolymers and studying structure-property relationships in constrained cyclic systems.

Quality Control

Our 1,1,2,2,9,9,10,10-Octafluoro[2.2]Paracyclophane is manufactured under strict quality systems to ensure batch-to-batch consistency critical for CVD processes. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. Quality is verified against stringent internal specifications designed to meet the high standards of the electronics and advanced materials industries.

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). Keep away from strong alkalis and incompatible materials. Due to its light-sensitive nature and value as a specialty chemical, long-term storage under inert atmosphere (e.g., argon or nitrogen) in a freezer (-20°C) is recommended for optimal stability.
