Description

3-[3-[(Trimethylsilyl)Oxy]Phenyl]Propenoic Acid Trimethylsilyl Ester is a high-purity, protected intermediate of significant value in advanced organic synthesis. Its dual trimethylsilyl (TMS) protecting groups offer enhanced stability and solubility, making it a crucial reagent for constructing complex molecular architectures. This compound is primarily sought by R&D and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors for the development of novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of complex drug candidates, particularly those containing substituted cinnamic acid or chalcone scaffolds.
• Agrochemical Synthesis: Used in the research and development of new-generation herbicides, fungicides, and plant growth regulators.
• Advanced Material Precursor: Serves as a monomer or cross-linking agent in the production of specialty polymers, liquid crystals, and organic electronic materials.
• Organic Synthesis Reagent: A versatile protected synthon for Friedel-Crafts alkylation, Heck coupling, and other palladium-catalyzed cross-coupling reactions.
• Flavor & Fragrance Chemistry: Intermediate for the synthesis of specific aromatic compounds used in high-value fragrance and flavor formulations.
• Academic & Industrial R&D: Essential for methodological development and scale-up studies in university and corporate research laboratories.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for high-purity synthetic intermediates. Every batch is characterized using advanced analytical techniques including HPLC, GC, NMR, and IR spectroscopy to confirm identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

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