Product Details
Depending on its state, this compound appears as white flakes or a molten substance. It is highly soluble in water and a range of organic solvents, including chlorinated solvents, petroleum-based hydrocarbons, cyclohexene, and common aromatic solvents such as benzene. Additionally, it dissolves readily in alcohols like methanol and ethanol, as well as in ethers. Owing to its versatile solubility profile, this substance is widely used in various industrial applications, including as a solvent in chemical processes, in the formulation of coatings and adhesives, and as a medium in polymer synthesis. Its solubility in both polar and nonpolar solvents makes it particularly valuable in processes that require diverse solvent interactions.
Furthermore, the compound's ability to dissolve in petroleum hydrocarbons and chlorinated solvents allows for its inclusion in formulations for cleaning, degreasing, and other specialized chemical treatments. Despite its broad solubility range, it exhibits minimal solubility in water, which can be advantageous in certain applications that require non-aqueous systems.
