Description
n-Hexane is an aliphatic hydrocarbon solvent offered in ROTIDRY® grade with a minimum purity of 99 % and a maximum water content of 50 ppm. It is defined by CAS number 110-54-3 and empirical formula C₆H₁₄, with a molar mass of 86,18 g/mol, a density of 0,66 g/cm³, a flash point of −22 °C and a boiling range of 68 to 69 °C. Supplied in a 1 l glass bottle from manufacturer Carl ROTH, this low-water n-hexane is suited to extractions, chromatography support and organic laboratory work where controlled residual moisture is preferred. The ROTIDRY® specification provides a dry, high-assay medium for sample preparation and synthetic steps that benefit from limited water content. Density and boiling data assist method development, solvent exchange and concentration under reduced pressure. Research and routine laboratories choose this grade when consistent dryness and assay support reproducible partitioning and non-polar solvent applications. Observe standard precautions for flammable hydrocarbon solvents, including adequate ventilation and ignition-source control during use and storage.
This article belongs on Dry & deuterated solvents (NMR, synthesis), in Solvents.

Questions about n-Hexane, ROTIDRY®, min. 99 % (max. 50 ppm H2O), 1 l, glass
What is this article?
n-Hexane, ROTIDRY®, min. 99 % (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.
