Packaging and shipping
Tetrahydrofuran is a colorless, transparent, low-viscosity, volatile, and ether-like-smelling five-membered ring ether. Its unique molecular structure endows it with extremely strong polarity and solubility, a low boiling point, and excellent swelling properties for numerous high-molecular materials, making it a “universal solvent” and core raw material monomer that connects multiple key industrial chains such as polyurethane elastomers, high-end pharmaceutical synthesis, high-performance adhesives, and new energy battery materials.

Delivery&Payment method
Anhui Eapearl Chemical Co., Ltd., as a company integrating sales and technical services, benefits from its geographical location advantage in the Yangtze River Economic Belt and its mature supply chain network. It is committed to providing customers with high-quality, multi-specification dimethyl sulfoxide (DMSO) products and professional application solutions.
Dimethyl sulfoxide (DMSO), with the chemical formula C₂H₆OS, is a colorless transparent liquid at room temperature that has a faint special odor. It is an hygroscopic liquid with extremely high polarity, a high boiling point (189 °C), excellent thermal stability, non-protic properties, and the ability to dissolve in water and most organic solvents. It is thus known as the “universal solvent” in the industrial and academic fields. As an outstanding polar non-protic solvent, DMSO, with its strong solubility, low toxicity, and excellent biolipid permeability, has become an indispensable core raw material and functional additive in fields such as fine chemicals, biomedicine, information electronics, new energy, and high-end new materials manufacturing.
The application of DMSO spans multiple high-tech industries, and its downstream demand is evolving from “broad dispersion” to “high-end focus”.
Pharmaceuticals and Biotechnology (the largest demand area, accounting for approximately 38.7%):
Drug synthesis and intermediates: As an ideal solvent for difficult synthesis processes such as fluorination reactions and high-temperature ring closure reactions, it significantly improves reaction rates and product purity, and is an indispensable medium for producing key drugs such as fluoroquinolones.
Drug delivery and transdermal absorption: Utilizing its excellent membrane permeability, it can be used as a penetration enhancer for topical pain-relieving and anti-inflammatory ointments (such as Furahydrogel and Bone Friend Cream), significantly enhancing the efficacy of the medicine.
Cell and biological sample cryopreservation: As a standard cell cryoprotectant for a long time, it is used for the low-temperature preservation of precious biological samples such as stem cells and hybridoma cells.
Electronic chemicals (one of the fastest-growing fields):
As an ultra-pure solvent, it is used in the precise cleaning process in semiconductor manufacturing, the dilution and stripping of photoresist, and the cleaning of liquid crystal panels, with extremely high requirements for residual metal ions and particle control of the products.
High-performance synthetic fibers and new materials:
Carbon fiber precursor spinning: It is one of the most commonly used and superior solvents for preparing PAN-based carbon fiber precursors, directly affecting the quality of the precursor and the performance of the final carbon fiber.
Special polymer synthesis: Used for the synthesis and processing of high-molecular materials such as polyimide and special engineering plastics.
Petroleum chemistry and gas treatment:
As an efficient extraction solvent, it is used for extracting aromatics (such as benzene and toluene) from hydrocarbon mixtures, and for removing acidic gases (such as hydrogen sulfide) in natural gas and refinery gas.
Pesticides and fine chemicals:
As an efficient penetrant and solvent, it is used for preparing pesticides to enhance their efficacy; it is also a key solvent in the production of numerous fine chemicals such as dyes, fragrances, and coatings.
