Dimethyl Sulfoxide (DMSO) Supplier in Malaysia
- Also known as
- DMSO
- Methyl Sulfoxide
- Sulfinylbismethane
Dimethyl sulfoxide supplier for pharmaceutical, agrochemical, electronics, polymer, coatings and laboratory buyers in Malaysia. Also called DMSO, methyl sulfoxide and sulfinylbismethane, this high-boiling polar aprotic solvent is selected for strong solvency, water miscibility and process dissolving duty.
Commercial grades include industrial or technical DMSO for general synthesis and formulation, electronic grade for semiconductor and display cleaning or photoresist stripping, and pharmaceutical grade for higher-purity synthesis, formulation and selected laboratory or cryopreservation work. DMSO freezes near room temperature, so cool-storage solidification is a normal handling topic.
Process chemists use dimethyl sulfoxide as a reaction medium and co-solvent. Electronics lines specify it for cleaning and stripping, while polymer and fibre plants may use it for acrylic or polysulfone systems, and paint or cleaning formulators use it as a high-boiling solvent component.

Dimethyl Sulfoxide applications
Safety and handling
Store sealed in a cool, dry, well-ventilated area. DMSO freezes near room temperature in cool storage, so solidified material in drums is a normal handling condition rather than a product defect. Warm gently and follow the safety data sheet for the quoted grade. Supply is subject to applicable requirements.
Common questions about dimethyl sulfoxide
What is dimethyl sulfoxide (DMSO) used for?
DMSO is a high-boiling polar aprotic solvent used in pharmaceutical synthesis and formulation, agrochemical blends, electronics cleaning and photoresist stripping, polymer and fibre processing, paint stripping and laboratory reagent work. State the application when enquiring so the grade can be matched to the duty.
Is DMSO the same as dimethyl sulfoxide?
Yes. DMSO is the universal trade abbreviation for dimethyl sulfoxide, also known as methyl sulfoxide or sulfinylbismethane. Keep it distinct from adjacent solvents such as dimethylformamide, dimethylacetamide, n-methyl-2-pyrrolidone and sulfolane, which are separate products.
Which DMSO grade should I request?
Industrial or technical grade suits general synthesis, agrochemical and routine process dissolving. Electronic grade is preferred for semiconductor and display cleaning or photoresist stripping. Pharmaceutical grade is selected for synthesis, formulation and higher-purity laboratory or cryopreservation duties. Send the target specification with the enquiry.
Why does DMSO sometimes solidify in the drum?
Dimethyl sulfoxide freezes near room temperature, so cool storage can turn liquid material into a solid or semi-solid mass. That is a normal physical behaviour, not a defect. Warm gently under controlled conditions and follow the handling guidance on the safety data sheet for the quoted grade.
What specifications matter when buying DMSO solvent?
Buyers commonly confirm appearance, assay, water content and any impurity or residue limits required by the process. Include the current specification, a sample requirement or the critical limits so the quoted grade can be checked against them.
What details are needed for a dimethyl sulfoxide price enquiry?
Provide the grade, application, target specification, quantity and delivery location. Mention preferred packing, documentation needs and timing so the quotation can address the complete requirement.
