Description

3,5-Dibromophenoxytrimethylsilane is a specialized organosilicon intermediate featuring a brominated aromatic ring. This compound matters for its dual functionality, serving as a versatile building block for introducing both silyl ether and bromoaryl groups into more complex molecular architectures. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key synthon in the development of novel active pharmaceutical ingredients (APIs), particularly for candidates requiring bromoaryl or silyl-protected phenolic motifs.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides where its structural elements contribute to biological activity.
• Liquid Crystal & OLED Materials: Serves as a precursor in the synthesis of brominated aromatic units for electronic and photonic materials, including liquid crystal displays and organic light-emitting diodes.
• Polymer Modification: Employed to functionalize polymers and resins, introducing bromine atoms for further cross-linking or flame-retardant properties, and silyl groups for surface modification.
• Cross-Coupling Reactions: The bromine atoms are reactive sites for palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira), enabling the construction of complex biaryl systems.
• Protecting Group Strategy: The trimethylsilyl (TMS) group acts as a protecting group for the phenolic oxygen, which can be selectively deprotected under mild conditions.

Quality Control

Our 3,5-Dibromophenoxytrimethylsilane is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and FTIR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided to support your quality assurance and regulatory needs.

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, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
