Description

Lys-Val Hydrochloride is a high-purity dipeptide derivative, specifically the hydrochloride salt of the Lysine-Valine dipeptide. This compound serves as a critical building block (protected amino acid) in solid-phase peptide synthesis (SPPS) and other advanced bioconjugation processes. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors who require reliable, high-quality intermediates for developing novel therapeutic peptides and biochemical probes.

Application

• Pharmaceutical Intermediate: Key raw material in the synthesis of complex therapeutic peptides and peptide hormones.
• Bioconjugation Reagent: Used to create peptide tags or linkers for antibody-drug conjugates (ADCs) and other targeted therapies.
• Biochemical Research: Serves as a standard or substrate in enzymatic studies and metabolic pathway research.
• Peptide Library Synthesis: A fundamental component for generating combinatorial peptide libraries for drug discovery and screening.
• Cosmetic Peptides: Potential intermediate for the production of bioactive peptides used in advanced skincare formulations.
• Academic & Industrial R&D: Essential for universities and contract research organizations (CROs) conducting peptide-related studies.
