설명

일반 설명

4-Mercaptobenzoic acid (4-MBA), also known as 4-Carboxythiophenol or p-Mercaptobenzoic acid, is an aromatic compound used in organic synthesis. 4-MBA promotes the formation of disulfide bonds through its reactive thiol (-SH) group. The sulfur atom in the thiol group is highly nucleophilic, allowing it to attack electrophiles.  facilitates the formation of diverse thiol-containing compounds.  Additionally, 4-MBA serves as a ligand to form coordination complexes and is utilized for surface functionalization, particularly in creating self-assembled monolayers (SAMs) on metal surfaces.

애플리케이션

• SERS substrate for food adulteration detection: 4-Mercaptobenzoic acid was employed in the layer-by-layer biopolymer assembly for the in situ fabrication of AuNP plasmonic paper, serving as a SERS substrate useful in detecting food adulteration (Viriyakitpattana et al., 2024).
• Development of magneto-plasmonic nanoparticles: Research highlighted the use of 4-Mercaptobenzoic acid in the multiwavelength SERS of magneto-plasmonic nanoparticles, obtained through combined laser ablation and solvothermal methods, showing versatility in nanoparticle synthesis (Talaikis et al., 2023).
