PEG13 is a polymer consisting of ethylene glycol subunits with two terminal hydroxyl groups. The hydroxyl groups can undergo reactions to further derivatize the compound. The hydrophilic properties of the PEG linker increases the water solubility properties of attached compounds in aqueous media.
Methyl 4-aminothiophene-3-carboxylate hydrochloride serves as a versatile building block in heterocyclic synthesis, enabling efficient access to bioactive thiophene scaffolds. The amine and ester functionalities offer orthogonal reactivity for derivatization, while the hydrochloride salt enhances bench stability and solubility. This compound facilitates straightforward functional group interconversions and participates reliably in coupling reactions, making it well-suited for medicinal chemistry and process development workflows.
