Description
Toluene is an aromatic laboratory solvent in ROTIDRY® grade with a minimum purity of 99,5 % and a maximum water content of 50 ppm. It is identified by CAS number 108-88-3 and empirical formula C₇H₈, with a molar mass of 92,14 g/mol, a density of 0,87 g/cm³, a flash point of 4,4 °C and a boiling point of 110,6 °C. Packaged in a 1 l glass bottle from manufacturer Carl ROTH, this dry toluene supports organic synthesis, extractions and analytical preparation where low residual water is advantageous. The ROTIDRY® specification delivers a high-assay, low-moisture medium suitable for reaction chemistry and sample work-up that benefit from controlled dryness. Boiling point and density values aid solvent selection, exchange and recovery steps in preparative workflows. Laboratories use this grade when reproducible water content and assay contribute to consistent performance in research and routine applications. Handle toluene according to standard laboratory practice for flammable aromatic solvents, ensuring adequate ventilation and appropriate personal protective measures throughout use.

Questions about Toluene, ROTIDRY®, min. 99,5 % (max.50 ppm H2O), 1 l, glass
What is this article?
Toluene, ROTIDRY®, min. 99,5 % (max.50 ppm H2O), 1 l, glass 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.
Which category should I open next?
The category is Solvents. The sub-category is Dry & deuterated solvents (NMR, synthesis). The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Technical & synthesis grade solvents and Green & alternative 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.
