Description
Diethyl ether ROTISOLV® Pestilyse® is a high-purity solvent grade with a minimum assay of 99,8 %, stabilised with ethanol for laboratory and chromatographic use. It carries CAS number 60-29-7 and empirical formula C₄H₁₀O, with 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, and the flash point is −40 °C, reflecting the highly volatile character typical of diethyl ether in GC solvent workflows. Supplied as 2,5 l in glass, this ROTISOLV® quality from manufacturer Carl ROTH is positioned for gas chromatography and related analytical applications that demand low-residue solvent performance. Supporting identifiers include EG number 200-467-2 and UN number 1155. The combination of Pestilyse® specification, ethanol stabilisation, and defined physical constants makes it a practical choice for GC sample preparation and solvent systems in analytical laboratories.
This article is part of HPLC & LC-MS grade solvents, in Solvents.

Questions about Diethyl ether, ROTISOLV®, min. 99,8 %, Pestilyse®, 2.5 l, glass
What is this article?
Diethyl ether, ROTISOLV®, min. 99,8 %, Pestilyse®, 2.5 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
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 HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), 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.
