Homobifunctional PEG Derivatives are polyethylene glycol polymers functionalized with identical reactive groups at both termini, synthesized via nucleophilic substitution or ring-opening polymerization. These reagents facilitate bioconjugation and polymer crosslinking. Specific molecular formulas and CAS numbers vary by chain length (e.g., mPEG-NHS) and require precise specification.
Store under inert atmosphere at -20°C to prevent hydrolysis. Avoid direct skin contact; use appropriate PPE due to potential sensitization. Clinical applications strictly adhere to GMP standards and regulatory purity thresholds.
