Description

Carbonic Acid, C,C'-1,4-Phenylene C,C'-Bis(1,1-Dimethylethyl) Ester is a specialized organic carbonate ester, a high-purity chemical intermediate of significant interest in advanced material synthesis. Its value lies in its role as a versatile building block for creating polymers and functional materials with enhanced thermal and chemical stability. This compound is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel products and formulations.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the multi-step synthesis of active pharmaceutical ingredients (APIs), particularly where a protected or functionalized aromatic core is required.
• Polymer Chemistry: Acts as a monomer or chain extender in the production of high-performance polycarbonates, polyurethanes, and other engineering plastics with specific optical or mechanical properties.
• Agrochemical Synthesis: Used in the research and development of advanced herbicides, fungicides, and plant growth regulators that require a sterically hindered phenolic derivative.
• Material Science Research: Employed in the development of novel organic frameworks, coatings, and adhesives where controlled reactivity and molecular architecture are critical.
• Cross-coupling Reactions: Functions as a substrate in palladium-catalyzed and other metal-mediated coupling reactions to construct complex biaryl systems.
• Liquid Crystal & OLED Materials: Investigated as a precursor for the synthesis of charge-transport or emissive layers in electronic display technologies.

Quality Control

Every batch of our Carbonic Acid, C,C'-1,4-Phenylene C,C'-Bis(1,1-Dimethylethyl) Ester is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation, to ensure compliance with exacting industry and customer specifications. Certificates of Analysis (COA) detailing all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
