Description

5-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Benzo[C][1,2,5]Oxadiazole is a high-value, heterocyclic boronic ester derivative, serving as a critical synthetic intermediate in modern organic chemistry. Its primary value lies in enabling efficient cross-coupling reactions, which are fundamental for constructing complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly for developing novel active ingredients and functional organic compounds.

Application

• Pharmaceutical Intermediate: Key building block in Suzuki-Miyaura cross-couplings for synthesizing drug candidates, especially those containing benzoxadiazole scaffolds with potential biological activity.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides by introducing the benzo[c][1,2,5]oxadiazole moiety into target molecules.
• Organic Light-Emitting Diodes (OLEDs): Acts as a precursor for electron-transport or emissive layer materials in OLED displays and lighting due to the electron-deficient nature of the benzoxadiazole unit.
• Polymer & Material Science: Employed in the synthesis of conjugated polymers and small molecules for organic electronics, including organic photovoltaics (OPVs) and field-effect transistors (OFETs).
• Ligand & Catalyst Development: Serves as a starting material for creating novel bidentate or tridentate ligands used in catalysis.
• Fluorescent Probe & Sensor Fabrication: Utilized to construct fluorescent markers and chemosensors for biological imaging or environmental detection.

Quality Control

Our 5-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Benzo[C][1,2,5]Oxadiazole is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and LC-MS, to ensure high chemical purity and structural identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to support your R&D and scale-up activities.

Storage

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