Verwenden
3-Mercaptopropionic acid is widely used in food and beverage industries as a flavoring agent. It is used in the production of PVC stabilizers, which are used as chain transfer agents in polymerizations. It can be used as primary or secondary, color stabilizer in combination with phenolic antioxidant for polymers. It acts as a sulfide ion equivalent and is utilized in the preparation of diaryl sulfide from aryl iodide.
Definition
ChEBI: A mercaptopropanoic acid that is propanoic acid carrying a sulfanyl group at position 3.
Application
3-Mercaptopropionic acid (3-MPA) is used to produce hydrophilic SAMs, which are terminated with carboxylic acids and can be further functionalized to introduce more complex end groups such as enzymes for biosensor applications. SAMs of 3-MPA are capped on ZnSe quantum dots for the electrochemical detection of dopamine. 3-MPA is used as a capping agent on CdTe quantum dot nanocrystals (QD NCs) for use as labeling materials in biomedical applications. It can also be used to modify the surface of iron oxide nanoparticles (Fe2O3) in the extraction and preconcentration of Al³⁺ and Cr³⁺ ions from different biological samples.
Allgemeine Beschreibung
3-Mercaptopropionic acid (3-MPA) is used as a self-assembled monolayer (SAM) with a thiol and carboxylic groups. It has short carbon chains and is mainly used as a capping agent on a variety of nanoparticles.
Biologische Aktivität
3-Mercaptopropionic acid is a blocking drug that causes an increase in sleep and a decrease in wakefulness. A related finding is that nipecotic acid also increases the time needed for isoflurane to induce loss of consciousness, whereas 3-mercaptopropionic acid decreases anesthesia induction time[1].
