Products Description
2-Hydroxyethyl-n-octyl sulfide, also known as MGK 874 or 2-(octylthio)ethanol, CAS 3547-33-9, is a clear pale yellow oily liquid with molecular formula C₁₀H₂₂OS. It is a well-established sulfur-containing insect repellent active ingredient. It repels pests rather than killing them, and is widely used in pest control formulations. Our regular specification is 90% min. It is insoluble in water but miscible with most organic solvents. It needs sealed storage away from strong oxidants. We support sample testing and bulk drum shipment, and can provide full set quality documents for global buyers.

Product Application
2-Hydroxyethyl-n-octyl sulfide (CAS No. 3547-33-9), also known as Bropol, is a versatile sulfur-containing compound with applications in insecticides, organic synthesis, and lubricant formulations. It can be used in insect repellent formulations to provide personal protection and support environmental pest management, while serving as an important sulfur-containing intermediate in the synthesis of various complex organic compounds. In the lubricant industry, it can function as an intermediate additive component, contributing to the performance and functional properties of base oils and metalworking fluids. In recent years, Bropol has also found expanding applications in animal feed, coatings, fur preservation, circulating water treatment in air-conditioning systems, sterilization of oilfield injection water, and disinfection of aircraft, vehicles, and marine vessels. The diversification of its application fields has further strengthened market interest and contributed to growing demand for the product.
