Product overview
Toluene (methylbenzene, toluol, CAS 108-88-3) is a clear, colorless liquid with a characteristic aromatic odor, insoluble in water and miscible with most organic solvents. Its strong solvency for resins, rubbers, oils and tars, moderate evaporation rate and low freezing point make it one of the most used aromatic solvents and an important feedstock for benzene, toluene diisocyanate and benzoic acid.
The grade supplied is specified at ≥ 99.9 % toluene by mass with ≤ 0.03 % benzene, ≤ 0.05 % C8 aromatics, ≤ 0.1 % non-aromatics, ≤ 2 ppm total sulfur, ≤ 3 mg/100 mL evaporation residue, ≤ 10 Hazen color, a neutral reaction and a density of 0.867 g/cm³. Water content is reported on each certificate of analysis.
Toluene boils at 110.6 °C and has a flash point of 4 °C closed cup (16 °C open cup); it is a highly flammable liquid transported as UN 1294. ChemPortal supplies it in steel drums, IBC totes and ISO tank containers.

Frequently asked questions
What benzene content does the toluene contain?
≤ 0.03 % by mass, which meets the requirements of most coating and adhesive producers that limit benzene for health and labeling reasons. The value is confirmed on the certificate of analysis for each lot.
What is the difference between toluene and xylene as solvents?
Toluene evaporates faster (boiling point 110.6 °C versus about 138–140 °C for xylene) and has slightly stronger solvency, so it is chosen for quick-drying adhesives and inks, while xylene is preferred for slower-drying alkyd and epoxy coatings.
How should toluene be stored?
In closed, grounded containers in a cool, well-ventilated area away from oxidizers and ignition sources; its flash point is 4 °C. Transport classification is UN 1294. Consult the SDS for exposure limits and protective equipment.
Which packaging options are available?
Steel drums, 1,000 L IBC totes and ISO tank containers. Send ChemPortal the required volume and destination port and we will quote delivered terms with lead time.
