Description

(+)-Allylboronic Acid Pinanediol Ester is a high-purity, chiral organoboron reagent essential for stereoselective synthesis. This compound matters because it enables the reliable and efficient construction of complex molecules with defined three-dimensional architecture, a critical requirement in modern pharmaceutical and agrochemical development. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, fine chemical, and advanced materials industries for applications such as asymmetric allylboration.

Application

• Asymmetric Synthesis: A key reagent for enantioselective allylboration reactions to install chiral allyl groups onto aldehydes and ketones.
• Pharmaceutical Intermediates: Used in the synthesis of chiral drug candidates and active pharmaceutical ingredients (APIs) requiring high stereochemical purity.
• Natural Product Synthesis: Facilitates the construction of complex natural products with multiple stereocenters.
• Agrochemical Development: Employed in creating chiral active ingredients for herbicides, fungicides, and insecticides.
• Ligand and Catalyst Preparation: Serves as a building block for novel chiral ligands and organocatalysts.
• Material Science Research: Used in the development of chiral polymers and advanced organic materials with specific optical properties.

Quality Control

Our (+)-Allylboronic Acid Pinanediol Ester is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high enantiomeric excess (ee). Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing purity, chiral purity (by chiral HPLC or GC), and identity confirmation. We adhere to cGMP standards where applicable, ensuring reliability for critical research and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., argon or nitrogen) due to its moisture-sensitive (hygroscopic) nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
