Description
Tetraethylene glycol monoamine is an amino-terminated oligo(ethylene glycol) reagent supplied at a minimum purity of 95 % for bioconjugation, surface chemistry, and linker synthesis. It is identified by CAS number 86770-74-3, empirical formula C₈H₁₉NO₄, and a molar mass of 193,24 g/mol. The short tetraethylene glycol chain combined with a primary amine terminus provides a hydrophilic spacer that improves solubility and reduces non-specific interactions in aqueous and mixed-solvent systems. The defined chain length aids batch-to-batch consistency when stoichiometric control of amine-reactive partners is essential. Researchers in medicinal chemistry, diagnostics, and materials science can integrate the compound into established activation and coupling protocols. Intended for qualified laboratory use, tetraethylene glycol monoamine should be handled according to good laboratory practice. Verify compatibility with your reaction conditions and consult applicable safety information before opening or dispensing the material.

Questions about Tetraethylene glycol monoamine, min. 95 %, 2 g
What is this article?
Tetraethylene glycol monoamine, min. 95 %, 2 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.
