Description

[1,1':4',1''-Terphenyl]-4,4''-Dicarboxylic Acid,2',5'-Dimercapto- CAS NO 1675217-38-5 is a high-purity, multifunctional organic building block featuring a rigid terphenyl core with both carboxylic acid and thiol functional groups. This unique molecular architecture makes it a critical precursor for synthesizing advanced materials with tailored electronic and structural properties. It is primarily utilized by research and development teams in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel compounds, ligands, and functionalized surfaces.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for developing active pharmaceutical ingredients (APIs), particularly in creating complex molecular scaffolds for drug discovery programs.
• Metal-Organic Framework (MOF) Synthesis: Acts as a versatile organic linker due to its multiple coordination sites (carboxylates and thiols), enabling the construction of porous materials for gas storage, separation, and catalysis.
• Polymer & Material Science: Used to synthesize specialty polymers, liquid crystals, and advanced composites where the rigid terphenyl unit imparts thermal stability and the functional groups allow for cross-linking or further modification.
• Agrochemical Research: Employed in the development of new herbicides, fungicides, and plant growth regulators that require specific structural motifs for bioactivity.
• Surface Functionalization & Nanotechnology: The thiol groups allow for covalent attachment to metal surfaces (e.g., gold nanoparticles) and semiconductors, useful in sensor development and nanoelectronics.
• Ligand for Catalysis: Can be used to create novel chelating ligands for transition metal catalysts used in asymmetric synthesis and other organic transformations.
