Description

Tetrahydrofuran CAS NO 109-99-9 is a versatile, heterocyclic organic compound and a key polar aprotic solvent with excellent solvating power. Its primary value lies in its ability to dissolve a wide range of polymers and resins, making it indispensable for industrial synthesis and formulation. This chemical is critically needed by manufacturers in the pharmaceutical, polymer, and specialty chemical sectors for applications ranging from reaction media to PVC cement production.

Application

• Primary solvent for polyvinyl chloride (PVC) and other polymer cements and coatings.
• Essential reaction medium in Grignard reactions and organometallic synthesis.
• Key starting material and solvent in pharmaceutical manufacturing for active pharmaceutical ingredient (API) synthesis.
• Solvent of choice for printing inks, adhesives, and magnetic tape coatings.
• Extraction solvent in laboratory and industrial chemical processes.
• Precursor in the production of polytetramethylene ether glycol (PTMEG), used for spandex fibers and polyurethane elastomers.
• Mobile phase component in analytical chemistry and high-performance liquid chromatography (HPLC).

Quality Control

Our Tetrahydrofuran is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including Industrial, HPLC, and Anhydrous, each meeting specific industry requirements. Certificates of Analysis (COA) documenting purity, water content, and peroxide levels are provided with every shipment to guarantee compliance with your specifications.

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 light-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent peroxide formation and evaporation. Recommended storage temperature is 15-25°C.
