Description

16-Carboxyhexadecyl Disulfide, 99% is a high-purity, long-chain bifunctional organic compound featuring both a carboxylic acid and a disulfide group. This unique molecular structure makes it a valuable intermediate for synthesizing specialized surfactants, surface modifiers, and functional polymers. It is particularly sought after by R&D and production teams in the specialty chemicals, advanced materials, and pharmaceutical sectors for applications requiring precise molecular assembly and surface engineering.

Application

• Surface Modification Agent: Used to create self-assembled monolayers (SAMs) on metal or metal oxide surfaces (e.g., gold, silver) for corrosion inhibition, biocompatibility enhancement, or sensor development.
• Polymer & Material Science: Serves as a chain extender, cross-linking agent, or functional monomer for synthesizing disulfide-linked polymers, responsive hydrogels, and smart materials with redox-sensitive properties.
• Specialty Surfactant Synthesis: Acts as a key intermediate for producing novel anionic surfactants and emulsifiers with unique rheological and interfacial properties.
• Bioconjugation & Drug Delivery: Utilized in bioconjugation chemistry to link biomolecules (peptides, proteins) to carriers or surfaces via the reversible disulfide bond, which is cleavable under reducing conditions.
• Lubricant & Additive Formulation: Employed as an additive or precursor for high-performance lubricants where the disulfide group can provide extreme pressure (EP) properties.
• Nanoparticle Functionalization: Used to coat and stabilize nanoparticles, providing a carboxylic acid handle for further chemical attachment in diagnostic and therapeutic nano-platforms.
