Description

1,1'-(2-Ethyl-4,5-Dimethyl-1,3,2-Dioxaborolane-4,5-Diyl)Bisethanone CAS NO 74646-18-7 is a specialized organoboron compound featuring a dioxaborolane ring structure with ketone functional groups. This compound is valued as a versatile building block and reagent in advanced organic synthesis, particularly for the formation of carbon-boron bonds. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science sectors who require high-purity intermediates for complex molecule construction.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring boron-containing motifs for Suzuki-Miyaura cross-coupling reactions.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the boronate ester functionality is incorporated into the final product.
• Materials Science Research: Acts as a monomer or cross-linking agent in the development of boron-based polymers, resins, and advanced functional materials.
• Organic Synthesis Reagent: Employed as a protected form of a boronic acid or as a transesterification agent in complex multi-step synthetic routes.
• Chemical Biology Probes: Utilized in the creation of molecular probes and sensors that leverage boron's unique reactivity for detection and imaging applications.
• Catalyst Ligand Precursor: Can be used to synthesize novel ligand systems for transition metal catalysts used in asymmetric synthesis.

Quality Control

Our production of 1,1'-(2-Ethyl-4,5-Dimethyl-1,3,2-Dioxaborolane-4,5-Diyl)Bisethanone adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. All materials undergo comprehensive analysis including HPLC, NMR, and IR spectroscopy to confirm identity and purity. A detailed Certificate of Analysis (COA) documenting all specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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. Keep away from incompatible materials.
