Description

Biphenyl-3-Carbonyl Chloride is a high-purity aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its high reactivity, enabling efficient formation of amide and ester bonds to construct complex molecular architectures. This intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with biphenyl scaffolds.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and insecticides that require specific biphenyl-based structures.
• Liquid Crystal & OLED Materials: Acts as a precursor for synthesizing biphenyl-based monomers and polymers used in display technologies.
• Polymer Chemistry: Employed as a monomer or cross-linking agent to introduce rigid biphenyl units into polymer backbones, enhancing thermal and mechanical properties.
• Organic Ligand Synthesis: Building block for creating complex ligands used in catalysis and metal-organic frameworks (MOFs).
• Dye & Pigment Manufacturing: Intermediate in the production of high-performance dyes and organic pigments.
• Custom Synthesis & R&D: A versatile starting material for contract research organizations and academic laboratories exploring new chemical entities.

Quality Control

Our Biphenyl-3-Carbonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, alcohols, and water.
