Description
Tetrahydrofuran is a cyclic ether offered at min. 99.5 % purity for synthesis, stabilised with BHT. With CAS number 109-99-9 and empirical formula C₄H₈O, it has 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, reflecting its high volatility and flammability profile in organic laboratories. This grade is intended for synthesis work where THF serves as a versatile aprotic solvent for organometallic reactions, polymer chemistry, and extractions. provides a practical volume for routine bench use. Material from manufacturer Carl ROTH is characterised with EG number 203-726-8 for regulatory traceability. Stabilisation with BHT helps maintain quality during storage and handling under appropriate laboratory conditions. Users value tetrahydrofuran for dissolving a wide range of polar and non-polar substrates in preparatory and process-oriented synthetic sequences.

Questions about Tetrahydrofuran , min. 99.5 %, for synthesis, 250 ml, glass
What is this article?
Tetrahydrofuran , min. 99.5 %, for synthesis, 250 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
