Description

Oc1801, 2,2'-(2,5-Dimethoxy-1,4-Phenylene)Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane) is a high-purity, functionalized aryl bis(boronic ester) building block essential for modern synthetic chemistry. This compound matters because it provides a protected boronic acid equivalent with enhanced stability, enabling precise Suzuki-Miyaura cross-coupling reactions under mild conditions. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex organic architectures.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and drug candidates via palladium-catalyzed cross-coupling.
• Agrochemical Synthesis: Used in the production of novel herbicides, fungicides, and insecticides requiring specific aryl-aryl linkages.
• Organic Electronic Materials: Enables the construction of conjugated polymers and small molecules for OLEDs, OFETs, and perovskite solar cells.
• Ligand and Catalyst Development: Serves as a precursor for creating sophisticated chelating ligands and organometallic catalysts.
• Chemical Biology Probes: Utilized in the synthesis of bioconjugates and molecular probes for target identification and validation.
• Polymer Chemistry: Facilitates the synthesis of specialty polymers with tailored optical or electronic properties.

Quality Control

Our Oc1801 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Every lot undergoes rigorous analytical testing, including NMR, HPLC, and GC analysis, to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) with detailed specifications are provided for each shipment, supporting compliance with cGMP and ISO 9001 standards for research and commercial use.

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., nitrogen or argon) due to its hygroscopic and light-sensitive nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
