Description

Tetrahydrofuran (Stabilized) is a versatile, high-purity cyclic ether solvent essential for industrial and research applications. Its stabilized formulation is critical to prevent peroxide formation, ensuring safe handling and extended shelf life for demanding processes. This product is indispensable for manufacturers in the pharmaceutical, polymer, and specialty chemical sectors who require a reliable, high-quality solvent for synthesis, extraction, and as a reaction medium.

Application

• Polymer Industry: Primary solvent for polyvinyl chloride (PVC) and as a crucial reaction medium for the polymerization of tetrahydrofuran to produce polytetramethylene ether glycol (PTMEG), a key component of spandex fibers and polyurethane elastomers.
• Pharmaceutical Synthesis: Widely used as an aprotic solvent for Grignard reactions, hydroboration, and other organometallic chemistries requiring anhydrous conditions.
• Chemical Manufacturing: Serves as an intermediate and solvent in the production of succinic acid, 1,4-butanediol, and other fine chemicals.
• Adhesives & Coatings: Effective solvent for resins and cellulose esters, used in the formulation of specialty adhesives, paints, and coatings.
• Laboratory & Research: Common solvent for chromatography and spectroscopy, as well as for recrystallization and extraction procedures.
• Electronics: Used in the production of magnetic tapes and as a cleaning agent for precision electronic components.

Quality Control

Our Tetrahydrofuran (Stabilized) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity specifications, including verification of stabilizer content to prevent peroxide formation. Certificates of Analysis (COA) detailing purity, water content, peroxide value, and other critical parameters are provided with every shipment to guarantee traceability and consistency for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and monitor for peroxide formation. Keep away from strong oxidizers and acids. Recommended storage temperature: 15-25°C.
