3-Mercaptopropionic acid is an organic compound containing both a thiol (-SH) and carboxylic acid (-COOH) functional group. It is commonly manufactured through the reaction of acrylonitrile with hydrogen sulfide, followed by hydrolysis. Due to its high reactivity, it is also employed in the creation of self-assembled monolayers (SAMs) on gold surfaces in nanotechnology.

Industrial Uses

1. Agrochemicals

Plant Growth Regulator: 3-Mercaptopropionic acid has potential applications as a plant growth regulator, influencing the sulfur metabolic pathways important for plant health.
Pesticide Intermediate: It can be used as an intermediate in the synthesis of sulfur-based pesticides, contributing to the development of products aimed at controlling agricultural pests.

2. Energy

Corrosion Protection: 3-Mercaptopropionic acid is used in oil drilling and refining processes as a corrosion inhibitor. Its chemical structure allows it to form a protective layer on metal surfaces, reducing the rate of corrosion in pipelines and equipment exposed to harsh environmental conditions.
Catalyst in Oil Refining: It can also serve as a catalyst modifier, helping to improve the efficiency and selectivity of refining processes in the petrochemical industry.

3. Water Treatment

Heavy Metal Chelation: 3-Mercaptopropionic acid can act as a chelating agent in water treatment processes to bind and remove heavy metals from wastewater. Its sulfur-containing thiol group effectively interacts with metals like mercury, lead, and copper, making it valuable for environmental remediation.

4. Polymer & Resins

Curing Agents & Crosslinkers : 3-MPA is suitable as a crosslinking agent for acrylic acid ester polymers. By introducing thiol groups into the polymer matrix, it facilitates the formation of crosslinked networks, enhancing the mechanical strength, chemical resistance, and thermal stability of the resulting materials.The thiol groups in 3-MPA can react with epoxy groups, serving as a curing agent for epoxy resins. This reaction leads to the formation of crosslinked networks, which improve the mechanical properties and durability of epoxy-based materials.
UV-Curable Resins: 3-Mercaptopropionic acid (3-MPA) is utilized in UV-curable resin formulations as a chain transfer agent, effectively regulating polymerization to achieve desired molecular weights and properties. Additionally, its incorporation can enhance the refractive index of cured resins, benefiting optical applications.
