CAS 34404-36-9 — N-(alpha)-BOC-N-(epsilon)-Z-L-lysine hydroxysuccinimideester (Boc-Lys(Z)-OSu

N-(alpha)-BOC-N-(epsilon)-Z-L-lysine hydroxysuccinimide ester (Boc-Lys(Z)-OSu) is a protected amino acid derivative widely used in peptide synthesis and bioconjugation reactions for selective modification of proteins and other biomolecules. This reagent enables efficient coupling via its activated ester functionality, preserving lysine’s side chain while protecting the alpha-amino group for controlled peptide assembly. CAS 34404-36-9; molecular formula C23H31N3O8 (MW 477.51). Store at –15 to –20°C under inert atmosphere. Non-hazardous (no signal word). Molekula supplies Boc-Lys(Z)-OSu from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
