Cas no 153086-78-3 (Boc-NH-PEG2-C2-NH2)

Boc-NH-PEG2-C2-NH2 is a heterobifunctional PEG-based reagent featuring a Boc-protected amine at one terminus and a free amine at the other, linked by a short ethylene glycol spacer. This compound is widely utilized in bioconjugation and peptide synthesis due to its water solubility, flexibility, and controlled reactivity. The Boc group provides selective protection for the primary amine, enabling orthogonal deprotection strategies in multi-step syntheses. The PEG2 spacer enhances solubility and reduces steric hindrance, facilitating efficient coupling reactions. This reagent is particularly valuable in drug delivery, protein modification, and crosslinking applications, offering versatility in designing functionalized biomolecules with precise spacing and stability.
