Description
Tetrahydrofuran ROTISOLV® is an LC-MS grade solvent with a minimum purity of 99,9 % and is supplied not stabilised. The empirical formula is C₄H₈O, molar mass 72,11 g/mol and density 0,883 g/cm³; the boiling point is 65 °C and the flash point is −21,2 °C (CAS 109-99-9, EG nr. 203-726-8). Delivered in a 1 l glass bottle, this grade is directed at liquid chromatography–mass spectrometry workflows that require a high-purity, non-stabilised THF background. Low boiling point and the stated density support its use as an organic solvent component in LC-MS method work where residual stabilisers are undesirable. The product comes from manufacturer Carl ROTH within the ROTISOLV® solvents for chromatographic and LC-MS applications, providing laboratories with a defined min. 99,9 % tetrahydrofuran option for sensitive mass-spectrometric detection.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Tetrahydrofuran, ROTISOLV®, min. 99,9 %, LC-MS, not stabilised, 1 l, glass
What is this article?
Tetrahydrofuran, ROTISOLV®, min. 99,9 %, LC-MS, not stabilised, 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.
