Monomethyl sebacate is primarily used as an intermediate in the synthesis of various chemicals, including plasticizers, lubricants, and polymers. It serves as a key component in the production of sebacic acid esters, which are valued for their low-temperature flexibility and stability, making them suitable for use in industrial lubricants and hydraulic fluids. Additionally, it is employed in the manufacturing of cosmetics and personal care products, where it acts as an emollient or skin-conditioning agent, providing smoothness and moisture retention. In the pharmaceutical industry, it is utilized as an excipient in drug formulations to enhance the delivery and stability of active ingredients. Its versatility also extends to the production of biodegradable materials, contributing to environmentally friendly applications.
