Description

Methyltetrahydrofuran (CAS NO 25265-68-3) is a versatile, water-immiscible cyclic ether solvent prized for its favorable environmental and safety profile compared to traditional options. Its core value proposition lies in being a highly volatile and renewable solvent that offers excellent solvency for a wide range of organic compounds. This makes it an essential material for industries focused on green chemistry, pharmaceuticals, and high-performance polymer synthesis, where process efficiency and sustainability are paramount.

Application

• Pharmaceutical Synthesis & Extraction: A key solvent for Grignard reactions, metal hydride reductions, and as a replacement for tetrahydrofuran (THF) in various reaction steps and purification processes.
• Polymer & Resin Manufacturing: Used in the production and processing of polymers, resins, and adhesives, particularly where a high-boiling, aprotic solvent with low water miscibility is required.
• Specialty Chemical Synthesis: Employed as a reaction medium for organometallic chemistry, polymerization initiators, and in the synthesis of fine chemicals and agrochemical intermediates.
• Analytical Chemistry & Laboratory Use: Serves as an effective solvent for chromatography, spectroscopy, and as a component in various analytical reagent formulations.
• Cleaning & Degreasing Agent: Utilized in precision cleaning applications for electronic components and metal parts due to its strong solvency and favorable evaporation rate.
• Renewable Fuel & Bio-based Chemical Production: Acts as a derivatization agent and solvent in the processing of biomass and the production of biofuels like 2-methyltetrahydrofuran.

Quality Control

Our Methyltetrahydrofuran is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and assay, Karl Fischer titration for water content, and identity confirmation (IR/GC-MS) to ensure it meets exacting specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your quality requirements.

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) to maintain purity and prevent peroxide formation. Keep away from strong oxidizing agents and acids. Recommended storage temperature: 15-25°C.
