Description

4-Butylthiophenylboronic Acid is a high-purity organoboron reagent, specifically a boronic acid derivative, widely utilized in modern synthetic chemistry. Its core value lies in its critical role as a key building block in cross-coupling reactions, enabling the efficient construction of complex molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials industries, where precise molecular assembly is paramount.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A fundamental reagent for forming carbon-carbon bonds between aryl or vinyl halides and boronic acids, crucial for synthesizing biaryl structures.
• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing thiophene and aryl motifs.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides that require specific aryl-thiophene architectures.
• Material Science & Organic Electronics: A building block for creating conjugated polymers and small molecules used in organic light-emitting diodes (OLEDs), field-effect transistors (OFETs), and photovoltaic cells.
• Ligand Synthesis: Can be utilized to prepare novel ligands for catalysis or metal-organic frameworks (MOFs).
• Chemical Biology & Proteomics: Potential use in the development of chemical probes and inhibitors for biological target identification.
