used in a variety of oxidation processes; industrially, is used as a starter of radical polymerization: Tetrahydrofuran: one of the most polar ethers; a useful solvent; its main use is as a precursor to polymers Tetrakis(triphenylphosphine)palladium(0) a catalyst for palladium-catalyzed coupling reactions Tetramethylammonium hydroxide
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic.
A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. [2]
Pharmaceutical formulation, in pharmaceutics, is the process in which different chemical substances, including the active drug, are combined to produce a final medicinal product. The word formulation is often used in a way that includes dosage form .

Depending on the solvents used, emulsions can form, and the time needed for the layers to separate can be extended if the mixing between solvents is not optimal. When adding organic solvent to aqueous, stoichiometry must be considered again, as the excess of water could hydrolyze organic compounds in only mildly acidic or basic conditions. In ...
Cosolvents improve solubility between non-miscible phases, as demonstrated by a solute dissolved in organic solvent but insoluble in water (left). A cosolvent miscible in both phases and able to dissolve the solute is added to form a homogeneous solution of water, organic solvent, and compound (right).
