Description

Ethanone, 1-[5-(1,1-Dimethylethyl)-2-Ethyl-4-Methyl-1,3,2-Dioxaborolan-4-Yl]- is a specialized organoboron compound featuring a dioxaborolane ring, a key structural motif valued in advanced synthetic chemistry. This compound serves as a crucial high-purity building block or intermediate for the development of pharmaceuticals, agrochemicals, and novel organic materials. It is primarily sought by R&D chemists and process development scientists in fine chemical and pharmaceutical industries for applications in cross-coupling reactions, medicinal chemistry, and material science research.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds.
• Agrochemical Research: Serves as a key precursor in developing new herbicides, fungicides, and insecticides with novel modes of action.
• Material Science: Employed in the creation of organic electronic materials, such as OLED (Organic Light-Emitting Diode) components and conductive polymers.
• Chemical Synthesis: Acts as a protected boronic ester reagent for introducing complex ketone-functionalized fragments into target molecules with high selectivity.
• Catalyst Ligand Precursor: Can be utilized to develop novel ligand systems for transition metal catalysis.
• Academic & Industrial R&D: A valuable tool for methodological development and exploring new synthetic pathways in organic chemistry laboratories.

Quality Control

Our production of Ethanone, 1-[5-(1,1-Dimethylethyl)-2-Ethyl-4-Methyl-1,3,2-Dioxaborolan-4-Yl]- adheres to stringent internal quality standards to ensure batch-to-batch consistency and high chemical purity suitable for research and development. Each lot is characterized by advanced analytical techniques including NMR, HPLC, and GC to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

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. Keep away from heat and incompatible materials.
