Description
Tetrahydrofuran ROTIDRY® plus is a high-purity cyclic ether solvent with a minimum assay of 99,5 % and a maximum water content of 50 ppm (CAS number 109-99-9). The empirical formula is C₄H₈O, the molar mass is 72,11 g/mol and the density is 0,883 g/cm³. Boiling point and flash point are 65 °C and −21,2 °C respectively. Packaged in a 1 l glass bottle, this grade is dried with molecular sieve and stabilised with BHT to help maintain low residual moisture for demanding laboratory work. Typical uses include moisture-sensitive organic synthesis, organometallic and Grignard chemistry, polymer research and other processes that require anhydrous tetrahydrofuran. The ROTIDRY® plus specification from manufacturer Carl ROTH supports consistent outcomes where water interference must be tightly controlled. With EG number 203-726-8, this THF grade offers a practical anhydrous solvent option for research and development laboratories that need a dependable dry cyclic ether in convenient glass packaging for routine dispensing and controlled handling.
This article belongs on Dry & deuterated solvents (NMR, synthesis), in Solvents.

Questions about Tetrahydrofuran, ROTIDRY®, plus min. 99,5 % (max. 50 ppm H2O), 1 l, glass
What is this article?
Tetrahydrofuran, ROTIDRY®, plus 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.
