Description

5-Bromopentylboronic Acid is a valuable bifunctional organoboron building block, essential for modern synthetic chemistry. Its unique structure, featuring both a reactive boronic acid group and a terminal bromoalkyl chain, makes it a versatile intermediate for constructing complex molecules through cross-coupling and other transformations. This compound is particularly critical for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity intermediates for drug discovery and specialty chemical synthesis.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially for compounds requiring a pentyl linker or boron-containing motifs.
• Suzuki-Miyaura Cross-Coupling Reactions: Serves as a crucial boronic acid coupling partner for forming carbon-carbon bonds with aryl or vinyl halides, a fundamental reaction in medicinal chemistry.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that incorporate boron chemistry.
• Liquid Crystal & OLED Material Development: Acts as a building block for creating advanced organic electronic materials and display components.
• Polymer & Resin Modification: Employed to introduce functional boronic acid groups into polymer backbones for sensors or smart materials.
• Bioconjugation & Probe Synthesis: Useful in creating chemical probes and bioconjugates for biochemical research and diagnostics.

Quality Control

Our 5-Bromopentylboronic Acid is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and commercial synthesis. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality system is designed to meet the stringent requirements of cGMP and ISO standards for fine chemical production.

Storage

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