Description

3-Trifluoromethylbenzenesulfinic Acid Sodium Salt is a high-purity organosulfur compound serving as a versatile synthetic intermediate. Its value lies in the unique reactivity of the sulfinate group, which can be leveraged for the introduction of the trifluoromethylphenyl moiety into more complex molecular architectures. This chemical is particularly needed by researchers and manufacturers in the pharmaceutical and agrochemical industries for developing novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those targeting central nervous system (CNS) disorders and inflammatory diseases.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides where the trifluoromethyl group enhances biological activity and stability.
• Ligand and Catalyst Development: Employed in organometallic chemistry to create novel ligands and catalysts for cross-coupling reactions and other catalytic processes.
• Material Science Research: Serves as a precursor for functionalized polymers, liquid crystals, and other advanced materials requiring specific electronic properties.
• Chemical Biology Probes: Utilized in the development of molecular probes and tags for studying biological systems and diagnostic applications.
• Custom Synthesis and Scale-up: A critical starting material for contract research and manufacturing organizations (CROs/CMOs) performing custom synthesis for clients.

Quality Control

Our 3-Trifluoromethylbenzenesulfinic Acid Sodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high chemical purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production standards.

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, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption. Keep away from strong acids and strong oxidizing agents.
