Heptaethylene Glycol Monomethyl Ether Chemical Properties,Usage,Production
Description
m-PEG7-alcohol is a PEG linker containing a hydroxyl group. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The hydrophilic PEG spacer increases solubility in aqueous media.
Uses
Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization
Definition
The presence of heptaethylene glycol monomethyl ether (HGME) as a process impurity and degradation impurity in the final purified form of Benzonatate is a determining factor in establishing the safety, identity, strength, purity, and quality of the drug substance. Owing to the cutaneous toxicity of HGME in the BNZ drug substance, a suitable and selective analysis method is required for its quantitation[1].
