Description
Tetrahydrofuran ROTISOLV® HPLC is an unstabilised high-purity solvent graded min. 99,9 % for demanding liquid chromatography work. With CAS number 109-99-9 and empirical formula C₄H₈O, it offers a molar mass of 72,11 g/mol and a density of 0,883 g/cm³. The boiling point is 65 °C and the flash point is −21,2 °C, properties that support controlled handling in analytical workflows. Physical data and identity parameters align with the specification from manufacturer Carl ROTH, including EG nr. 203-726-8. Laboratories use it as a mobile-phase component or sample solvent in HPLC methods that require an unstabilised tetrahydrofuran matrix. Clear labelling of purity, pack format and key constants helps method development and routine QC teams specify the correct grade for reproducible separations.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Tetrahydrofuran ROTISOLV® HPLC, unstabilised, min. 99.9 %, 1 l, glass
What is this article?
Tetrahydrofuran ROTISOLV® HPLC, unstabilised, min. 99.9 %, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
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 HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), 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.
