Description

11-Mercaptoundecyl Trifluroacetate, 99% CAS NO 138524-05-7 is a high-purity, functionalized organic compound featuring a long alkyl chain terminated with a thiol group protected by a trifluoroacetyl moiety. This product is critical for researchers and manufacturers requiring a stable, protected thiol precursor for advanced material synthesis and surface functionalization. It is primarily utilized in the development of self-assembled monolayers (SAMs), nanotechnology, and as a key intermediate in pharmaceutical and specialty chemical synthesis.

Application

• Surface Chemistry & Nanotechnology: A key precursor for creating self-assembled monolayers (SAMs) on gold, silver, and other metal surfaces for biosensors, corrosion inhibition, and surface modification.
• Pharmaceutical Intermediates: Serves as a protected thiol building block in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Polymer & Material Science: Used in the synthesis of functional polymers, cross-linking agents, and materials with tailored surface properties.
• Bioconjugation: The protected thiol can be deprotected for site-specific conjugation of biomolecules, peptides, or proteins in diagnostic and therapeutic applications.
• Lubricant & Additive Synthesis: Acts as an intermediate for creating high-performance lubricant additives and surfactants with specific functional groups.
• Research & Development: An essential reagent for academic and industrial R&D in organic synthesis, catalysis, and advanced material design.
