SLF-amido-C2-COOH is primarily utilized in the field of bioconjugation and chemical biology. It serves as a versatile linker molecule for attaching various functional groups or biomolecules, such as peptides, proteins, or fluorescent dyes, to a target molecule or surface. Its amide bond ensures stability, while the carboxyl group allows for further covalent modifications, making it suitable for creating tailored bioconjugates for research, diagnostics, or therapeutic applications. Additionally, it is often employed in the development of drug delivery systems, where precise attachment of targeting ligands or payloads is required for enhanced specificity and efficacy.
