This compound is a biotin derivative, specifically N-(2-hydroxyethyl)biotinamide, featuring the biotin core linked to a hydroxyethyl amide group for enhanced water solubility. It is primarily used in biochemical and pharmaceutical research as a conjugation reagent, leveraging the strong biotin-streptavidin binding for labeling biomolecules, targeted drug delivery systems, and molecular imaging techniques. The hydroxyethyl moiety allows easy modification with fluorescent dyes or radiolabels. In cosmetic applications, biotin derivatives like this support skin and hair health by aiding keratin infrastructure, improving hydration, and promoting wound healing through cell regeneration. It is stable across various pH and temperature conditions, suitable for incorporation into serums, creams, and research formulations.
