Description
Dimethyl sulphoxide (DMSO), SOLVAGREEN®, is a synthesis-grade solvent supplied at min. 99% purity from recycled material, with empirical formula C₂H₆OS and CAS number 67-68-5. The molar mass is 78,13 g/mol, density 1,1 g/cm³, flash point 87 °C and boiling point 189 °C, giving a well-characterised polar aprotic medium for organic synthesis, dissolution steps and general laboratory solvent use. This variant is SOLVAGREEN® DMSO is positioned for synthesis applications where a high minimum assay and defined physical data are required. Laboratories use it for reaction media, stock solutions and work-up procedures that benefit from the solvating power of DMSO. The product (Carl ROTH) carries EG nr. 200-664-3 and fits solvent workflows in chemical synthesis and related research. Clear specification of purity, molar mass and thermal properties helps method transfer and documentation in regulated or quality-conscious environments without extending beyond the stated synthesis grade.
This article is part of Green & alternative solvents, in Solvents.

Questions about Dimethyl sulphoxide (DMSO), 1 l, glass, >=99,0 %, for synthesis
What is this article?
Dimethyl sulphoxide (DMSO), 1 l, glass, >=99,0 %, for synthesis is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Green & alternative solvents, inside Solvents, in Lab chemicals.
A green or alternative solvent is chosen to replace a more hazardous one, often with a higher boiling point or a different polarity. It is not automatically equivalent in a method. The replacement has to dissolve the same compounds and leave the same impurities behind, which is a test, not a label.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Green & alternative solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis) and Technical & synthesis grade solvents.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
