Description

4,4,5,5-Tetramethyl-2-(4-(Pentyloxy)Phenyl)-1,3,2-Dioxaborolane CAS NO 1174548-77-6 is a high-purity, advanced boronic ester derivative, a critical intermediate in modern synthetic chemistry. Its primary value lies in enabling efficient Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing complex biaryl and heterobiaryl structures. This compound is essential for researchers and manufacturers in pharmaceutical development, agrochemical synthesis, and materials science, particularly in the production of liquid crystals and organic light-emitting diodes (OLEDs).

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 advanced herbicides, fungicides, and insecticides requiring specific biaryl motifs.
• Materials Science: Crucial precursor in the manufacture of organic electronic materials, including charge-transport layers and emitters for OLED displays and lighting.
• Liquid Crystal Manufacturing: Serves as a synthetic intermediate for creating liquid crystal molecules used in LCD screens.
• Academic & Contract Research: Enables novel chemical space exploration in academic laboratories and CROs (Contract Research Organizations) for discovery chemistry.
• Polymer Chemistry: Can be incorporated into polymer backbones to create functional materials with tailored electronic or optical properties.

Quality Control

Every batch of 4,4,5,5-Tetramethyl-2-(4-(Pentyloxy)Phenyl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for sensitive cross-coupling reactions. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as purity (by HPLC/NMR), identity confirmation, and impurity profiles. Our quality commitment supports compliance in cGMP and ISO 9001 environments for advanced intermediate supply.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to maintain optimal reactivity. Keep away from heat and incompatible materials.
