Description

T-Boc-Cystamine CAS NO 485800-26-8 is a protected derivative of cystamine, featuring a tert-butoxycarbonyl (Boc) group, which serves as a critical amine-protecting reagent in organic synthesis and bioconjugation. This compound is essential for researchers and manufacturers requiring controlled amine reactivity, particularly in the development of peptide-based pharmaceuticals and advanced drug delivery systems. It is primarily utilized by professionals in pharmaceutical R&D, biotech, and fine chemical synthesis for creating stable intermediates and cross-linked biomaterials.

Application

• Key intermediate in the solid-phase peptide synthesis (SPPS) of complex peptides and proteins.
• Building block for the synthesis of drug-linker conjugates used in Antibody-Drug Conjugates (ADCs) and targeted therapies.
• Reagent for introducing disulfide bridges or thiol-reactive sites into biomolecules for structural stabilization.
• Cross-linking agent in the development of biodegradable polymers and hydrogels for controlled drug release.
• Starting material for the preparation of functionalized surfaces and nanoparticles for diagnostic assays.
• Research chemical in proteomics and chemical biology for studying protein-protein interactions and labeling.
