Description
Tetrahydrofuran ROTIDRY® Sept is a dry-grade cyclic ether solvent supplied at min. 99,8 % purity with a maximum water content of 50 ppm and stabilised with BHT. Identified by CAS number 109-99-9 and empirical formula C₄H₈O, it has a molar mass of 72,11 g/mol, a density of 0,883 g/cm³, a boiling point of 65 °C and a flash point of −21,2 °C. This 250 ml pack is intended for moisture-sensitive synthetic and analytical work where low residual water is essential, including organometallic reactions, polymer chemistry and anhydrous sample preparation. The ROTIDRY® Sept presentation supports controlled withdrawal while helping maintain dryness during use. Physical constants and identity data from manufacturer Carl ROTH align with routine laboratory solvent specifications for tetrahydrofuran. With EG number 203-726-8 and UN number 2056, the material is clearly documented for laboratory handling and inventory control. Suitable for research and quality-control environments that require a defined, BHT-stabilised dry THF grade in a convenient small-volume format.

Questions about Tetrahydrofuran ROTIDRY®Sept,, min. 99,8 % (max. 50 ppm H2O), stab. BHT, 250 ml
What is this article?
Tetrahydrofuran ROTIDRY®Sept,, min. 99,8 % (max. 50 ppm H2O), stab. BHT, 250 ml 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.
