Description

Catecholborane is a versatile organoboron reagent widely used in organic synthesis. Its primary value lies in its ability to act as a hydroborating agent and a precursor to other boron-containing compounds, enabling critical carbon-boron bond formation. This makes it an essential material for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors seeking to create complex molecular architectures.

Application

• Hydroboration Reactions: Selective addition to alkenes and alkynes for the synthesis of organoboranes.
• Pharmaceutical Intermediates: Key reagent in the synthesis of active pharmaceutical ingredients (APIs) and complex drug candidates.
• Agrochemical Synthesis: Used in creating novel pesticides and herbicides through boron-mediated coupling steps.
• Polymer & Materials Science: Precursor for boron-based polymers, liquid crystals, and other functional materials.
• Catalyst & Ligand Preparation: Synthesis of boron-containing ligands for transition metal catalysis.
• Asymmetric Synthesis: Employed in stereoselective hydroboration reactions to produce chiral building blocks.
• Cross-Coupling Reagent: Acts as a boron source in Suzuki-Miyaura cross-coupling reactions.
• Research & Development: Fundamental reagent in academic and industrial R&D for exploring new synthetic methodologies.

Quality Control

Our Catecholborane is produced under stringent quality control protocols to ensure batch-to-batch consistency and high purity, meeting the exacting standards of synthetic chemistry applications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with each shipment. We adhere to cGMP principles where applicable to support our customers in regulated development environments.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Due to its moisture-sensitive and easily oxidized nature, the container must be kept sealed and handled under anhydrous conditions. Recommended storage temperature is 2-8°C for long-term stability.
