Description

3-{4-[(Trifluoromethyl)Thio]Phenyl}Acrylic Acid is a high-value, functionalized acrylic acid derivative characterized by its phenyl ring substituted with a trifluoromethylthio group. This unique structure makes it a versatile and critical building block in advanced organic synthesis, particularly for introducing lipophilic and electron-withdrawing motifs. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the development of active pharmaceutical ingredients (APIs), especially in protease inhibitors, kinase inhibitors, and other small molecule therapeutics.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides, where the trifluoromethylthio group enhances biological activity and metabolic stability.
• Material Science Precursor: Serves as a monomer or cross-linking agent in the synthesis of specialty polymers, liquid crystals, and advanced organic frameworks (MOFs/COFs).
• Chemical Biology Probe Development: Employed in designing photoaffinity labels, activity-based probes, and other tools for studying biological systems and drug-target interactions.
• Organic Electronics: A potential building block for electron-transport materials, non-linear optical (NLO) chromophores, and other components in OLEDs or organic semiconductors.
• Custom Synthesis & Contract Manufacturing: Supplied to CROs and CDMOs for custom synthesis projects requiring this specific fluorinated scaffold.

Quality Control

Our 3-{4-[(Trifluoromethyl)Thio]Phenyl}Acrylic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and KF titration for moisture content, to ensure it meets the high standards required for research and scale-up applications. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent quality.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
