Chemical Properties

Cream Colour Crystalline Solid

Uses

Gold nanostructures functionalized with 4-Mercaptobenzoic acid (4-MBA) may exhibit improve catalytic activity. Several studies report 4-MBA as a model analyte for surface enhancement Raman scattering (SERS) substrates.

General Description

4-mercaptobenzoic acid (4-MBA) is a probe molecule with thiol and carboxylic groups that form a self-assembled monolayers (SAMs) which can be used for the development of surface enhanced raman spectroscopy (SERS) sensors.
