Description

1,4-Benzenedicarboxylic Acid, 2,5-Bis[[[[4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]Methoxy]Carbonyl]Amino]-, 1,4-Diethyl Ester is a highly functionalized diester derivative of terephthalic acid, featuring two symmetrically positioned boronic ester (BPin) moieties and dual carbamate-protected amide linkages. It serves as a critical bifunctional building block for Suzuki-Miyaura cross-coupling in the synthesis of advanced conjugated polymers, covalent organic frameworks (COFs), and precision-engineered optoelectronic materials. This compound is essential for R&D laboratories and specialty chemical manufacturers developing high-performance OLED emitters, organic photovoltaic (OPV) acceptors, and stimuli-responsive supramolecular architectures.

Application

• Suzuki-Miyaura cross-coupling reactions to construct π-conjugated donor-acceptor polymers for organic light-emitting diodes (OLEDs)
• Synthesis of boron-containing covalent organic frameworks (COFs) with tunable porosity and luminescence
• Preparation of electron-transport layers (ETLs) in organic photovoltaics (OPVs) and perovskite solar cells
• Building block for sequence-controlled polyamides and boron-functionalized dendrimers
• Development of chemosensors and boronic acid-based fluorescent probes
• Monomer in palladium-catalyzed direct arylation polymerizations requiring orthogonal reactivity
• Research-grade intermediate for metal–organic framework (MOF) linker diversification

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches are verified for identity (IR, HPLC retention time), purity (≥98.5% by HPLC), residual solvents (meets ICH Q3C guidelines), and heavy metals (≤10 ppm total). Testing follows ISO/IEC 17025-accredited protocols where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store under inert atmosphere (nitrogen or argon) at 2–8 °C. Due to hygroscopic and oxidation-sensitive nature, minimize exposure to ambient air and moisture. Maintain relative humidity below 30% during handling and storage. Ensure adequate ventilation in storage areas.
