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.
