Product Description
The product appears as white flakes in its solid state and as a molten liquid when heated. It exhibits good solubility in a wide range of organic solvents, including chlorinated solvents, petroleum-based hydrocarbons, aromatic solvents, alcohols, and ethers.
It is also readily soluble in common solvents such as methanol and ethanol, providing excellent formulation flexibility across different processing systems. Its broad solvent compatibility makes it suitable for various industrial applications, including chemical processing, coatings, adhesives, and polymer synthesis.
The ability to interact with both polar and non-polar solvents makes this material particularly useful in formulations and processes requiring flexible solvent selection and good compatibility.
The compound is readily soluble in petroleum hydrocarbons and chlorinated solvents, making it suitable for formulations used in cleaning, degreasing, and specialized chemical treatment processes.
It has limited solubility in water, which makes it particularly suitable for non-aqueous formulations and solvent-based systems where low water solubility and compatibility with organic solvents are required.
