Description
Poly(ethylene glycol) diglycidyl ether is a bifunctional epoxide-terminated polyethylene glycol reagent offered at a minimum purity of 95 %. It is registered under CAS number 26403-72-5 and exhibits a density of 1,14 g/cm³ together with a flash point of 197 °C. The material is Reactive diglycidyl end groups enable covalent coupling to nucleophilic functionalities under controlled conditions. This grade from manufacturer Carl ROTH supports formulation work, materials research, and bioconjugation-oriented experiments where a PEG-based diepoxide linker is required. Physical property data aid handling, process design, and safety assessment during scale-up from small trials. balances laboratory convenience with sufficient quantity for repeated preparations and optimisation series. Clear CAS identification and stated minimum purity help maintain consistency in experimental documentation and method transfer between teams.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Poly(ethylene glycol) diglycidyl ether, min. 95 %, 100 g
What is this article?
Poly(ethylene glycol) diglycidyl ether, min. 95 %, 100 g 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?
