Description

(2-Ethoxy-4-Formylphenyl)Boronic Acid is a high-purity boronic acid derivative featuring both an aldehyde and an ethoxy functional group on the aromatic ring. This bifunctional structure makes it a versatile and critical building block in modern synthetic chemistry, particularly for cross-coupling reactions and the construction of complex molecular architectures. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for creating novel active ingredients and functional polymers.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for forming carbon-carbon bonds in the synthesis of biaryl compounds, a common scaffold in pharmaceuticals and organic electronics.
• Pharmaceutical Intermediate: Serves as a precursor in the development of active pharmaceutical ingredients (APIs), especially for kinase inhibitors and other targeted therapies.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides requiring specific aryl-boronic acid intermediates.
• Material Science & OLED Development: Employed in the synthesis of organic light-emitting diode (OLED) materials and other advanced organic semiconductors.
• Chemical Biology & Probe Development: Utilized for bioconjugation and as a handle in the synthesis of molecular probes and diagnostic agents due to its reactive aldehyde and boronic acid groups.
• Academic & Contract Research: Essential for methodological development and exploratory synthesis in university and CRO (Contract Research Organization) laboratories.
