Used primarily in Karl Fischer (KF) titration for determining water content in aldehydes and ketones. This solvent ensures accurate and reliable measurements by providing a stable medium for the reaction. It is particularly effective in handling samples that are challenging to dissolve in standard KF solvents. Its application is crucial in industries like pharmaceuticals, chemicals, and food, where precise moisture analysis is essential for quality control. The solvent minimizes interference from aldehydes and ketones, making it a preferred choice for volumetric one-component KF titration in such matrices.
