Bifunctional thiol-carboxylic acid offering both strong metal chelation (Au, Ag, Cu, Fe) and surface self-assembly capability. Widely utilised for:
Fabrication of ordered SAMs on gold/silver to tune wettability, conductivity and biocompatibility of electrodes and biosensors ;
Preparation of monodisperse Au₂₅(SR)₁₈ nanoclusters and other metal NCs for catalysis and bio-imaging ;
Highly sensitive colorimetric/fluorimetric detection and pre-concentration of heavy-metal ions in environmental analysis;
Building block for metal-organic frameworks (MOFs), antibacterial agents, and benzothiazole UV-absorbers;
Derivatisation reagent for LC-MS quantitation of ethyl-mercury compounds.
Store sealed, dry and under argon; avoid strong acids/bases to prevent thio-ester hydrolysis.
