Biotin-PEG5-NH-BOC is widely used in bioconjugation and biochemical research due to its unique properties. The biotin moiety allows for strong binding with avidin or streptavidin, making it valuable in applications such as protein labeling, immobilization, and detection assays. The PEG5 linker enhances solubility and reduces steric hindrance, facilitating efficient conjugation with biomolecules. The NH-BOC (tert-butoxycarbonyl) protecting group ensures selective reactivity, enabling controlled modifications in multi-step synthesis processes. This compound is particularly useful in the development of biosensors, drug delivery systems, and targeted imaging agents, where precise and stable bioconjugation is essential. Its versatility also extends to surface functionalization in nanotechnology and the study of biomolecular interactions.
