Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization

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].
