Description

Methyl 4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Benzoate CAS NO 17136-80-0 is a high-purity, versatile boronic ester derivative, serving as a critical building block in modern synthetic chemistry. Its primary value lies in enabling efficient Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing complex biaryl and heterobiaryl structures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality intermediates for drug discovery, ligand synthesis, and functional polymer development.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing biphenyl or aromatic heterocycle motifs.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science: Precursor for creating organic electronic materials, such as those used in OLEDs (Organic Light-Emitting Diodes) and OFETs (Organic Field-Effect Transistors).
• Ligand and Catalyst Development: Serves as a starting material for synthesizing novel ligands for transition metal catalysis and organocatalysts.
• Chemical Research & Development: A reliable reagent for academic and industrial R&D labs exploring new C-C bond-forming methodologies and complex molecule synthesis.
• Liquid Crystal and Polymer Chemistry: Incorporated into monomers for producing specialty polymers and liquid crystalline materials with tailored properties.
