Description

General description

4,4′-Dimercaptostilbene is a dithiol molecule that can be coated on gold (Au) surfaces as it provides a rigid structure and has low susceptibility to chemical interactions. It modifies the surface of gold and enables an increase in enhancement factor (EF) for surface enhanced Raman spectroscopy.

Packaging

100 mg in glass insert
