This chemical is primarily used as a versatile intermediate in organic synthesis, particularly in the development of complex molecules. It is often employed in the preparation of polyethylene glycol (PEG) derivatives, which are widely utilized in the pharmaceutical industry for drug delivery systems. The compound's structure, featuring both a bromo group and a carboxylic acid, allows it to act as a linker or spacer in bioconjugation chemistry, facilitating the attachment of bioactive molecules to PEG chains. Additionally, it finds application in the creation of surfactants and emulsifiers due to its amphiphilic nature, enhancing the solubility and stability of various formulations in cosmetic and industrial products. Its role in modifying surface properties of materials also makes it valuable in coatings and nanotechnology applications.
