Used as an adsorbent for heavy metal removal in wastewater treatment due to its high affinity for metals like mercury, lead, and cadmium. The thiol groups bind strongly with soft metal ions, making it effective in environmental remediation.

Also applied in catalysis support where the functional group anchors metal catalysts or serves as a carrier in reactions requiring sulfhydryl groups, such as high-specificity organic synthesis.

Commonly used in solid-phase extraction for pre-concentrating trace metals prior to analysis and as a stationary phase in chromatography for separating sulfur-sensitive compounds.

Suitable for modifying surfaces in sensors for detecting metal ions, biological molecules, or positively charged toxins.

Applied in drug delivery systems by covalently binding drug molecules to the surface via mercapto groups, enabling precise controlled release.

Stable under a range of pH conditions, allowing use in diverse industrial processes.
