Description
Polyethylene glycol 600 is a higher-viscosity PEG liquid in ROTIPURAN® Ph.Eur. quality, identified by CAS number 25322-68-3 and EG number 500-038-2. The molar-mass range of 570–630 g/mol and density of 1,12 g/cm³ characterise a water-miscible polyether used as a solvent, plasticiser, lubricant base, and formulation component in chemical and life-science laboratories. Reported flash and boiling points are 138,6 °C and 205,7 °C, providing reference values for process and safety planning. This polyethylene glycol 600 from manufacturer Carl ROTH fits workflows that specify a Ph.Eur.-oriented grade with a clearly stated molar-mass band. Laboratories can rely on the listed physical data—molar mass, density, and thermal points—when matching PEG 600 to solubility, viscosity, or compatibility requirements across analytical and preparative applications.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Polyethylene glycol 600, ROTIPURAN® Ph.Eur., 1 l, plastic
What is this article?
Polyethylene glycol 600, ROTIPURAN® Ph.Eur., 1 l, plastic 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?
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.
How does ordering and shipping work?
