Description

4-Bromobutylboronic Acid is a valuable bifunctional organoboron building block, featuring both a reactive boronic acid group and a terminal bromoalkyl chain. This dual functionality makes it a critical intermediate for constructing complex molecular architectures via sequential cross-coupling and functionalization reactions. It is primarily utilized by researchers and process chemists in the pharmaceutical and agrochemical industries for the synthesis of active ingredients and novel chemical entities.

Application

• Pharmaceutical Intermediate: Key building block in Suzuki-Miyaura cross-coupling reactions for creating biaryl and alkyl-aryl linkages in drug candidates.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides requiring specific boron-containing motifs.
• Material Science: Serves as a monomer or linker in the synthesis of organic polymers and advanced functional materials.
• Ligand Preparation: Useful for synthesizing specialized bidentate or polydentate ligands for catalysis.
• Chemical Biology Probes: Employed in the design and synthesis of molecular probes and tags for bio-conjugation and imaging.
• Organic Synthesis: Versatile reagent for sequential functionalization, enabling the introduction of both boron and halogen handles for further diversification.

Quality Control

Our 4-Bromobutylboronic Acid is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality management system is designed to meet the stringent requirements of research and development as well as scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
