Description
Toluene is an aromatic hydrocarbon solvent supplied in ROTIDRY® Sept quality at minimum 99,5 % with a water specification of minimum 30 ppm H₂O. It is defined by CAS number 108-88-3, empirical formula C₇H₈ and a molar mass of 92,14 g/mol. Physical characteristics include a density of 0,87 g/cm³, a flash point of 4,4 °C and a boiling point of 110,6 °C, which are essential for safe handling and process design. This variant is packed as 250 ml in a septum bottle, enabling controlled withdrawal under inert or dry conditions for moisture-sensitive work. The low-water ROTIDRY® Sept grade suits anhydrous reactions, sample preparation and analytical applications where residual moisture must remain tightly controlled. The solvent is provided by manufacturer Carl ROTH for laboratory chemical use. With UN number 1294 and EG number 203-625-9, the product supports clear regulatory and logistics identification. Density and boiling-point data assist volume-to-mass conversions and distillation or evaporation planning in synthesis, chromatography sample work-up and general organic laboratory practice.

Questions about Toluene, ROTIDRY®Sept min.99,5% (min.30 ppm H2O), 250 ml, septum bottle
What is this article?
Toluene, ROTIDRY®Sept min.99,5% (min.30 ppm H2O), 250 ml, septum bottle is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dry & deuterated solvents (NMR, synthesis), inside Solvents, in Lab chemicals.
A dry solvent has had water removed to a stated level, for a reaction that water would stop. A deuterated solvent replaces hydrogen with deuterium so an NMR spectrum is not drowned by the solvent signal. The isotopic enrichment and the water content are the two specifications. Caps and septa matter, because either product picks up moisture from the air.
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.
