Description
Diethyl ether is a high-purity anhydrous laboratory solvent supplied as ROTIDRY®Sept grade with a minimum assay of 99,5 % and a maximum water content of 50 ppm H₂O. Identified by CAS number 60-29-7 and empirical formula C₄H₁₀O, it has a molar mass of 74,12 g/mol and a density of 0,71 g/cm³. The boiling point lies between 34,58 and 34,59 °C, while the flash point is −40 °C. This grade is stabilised with BHT to support handling stability. Packaged in a 250 ml septum bottle, the solvent is convenient for moisture-sensitive work, extractions, and organic synthesis where low residual water is required. Physical data and composition align with the specification from manufacturer Carl ROTH. Diethyl ether remains a versatile ether solvent for research and analytical laboratories that need a dry, well-characterised grade in a septum-sealed format for controlled withdrawal.
This article is part of Dry & deuterated solvents (NMR, synthesis), in Solvents.

Questions about Diethyl ether, ROTIDRY®Sept min. 99,5 % (max. 50 ppm H2O), 250 ml, septum bottle
What is this article?
Diethyl ether, ROTIDRY®Sept min. 99,5 % (max. 50 ppm H2O), 250 ml, septum bottle 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.
