N-Cyclohexyl-2-pyrrolidone or CHP[1] is a yellow to colorless liquid. It has a low vapor pressure, and is nearly odorless.[2] It has a low solubility in water, but is soluble in a variety of organic solvents.

CHP is used in the electronics industry as a photoresist stripper (usually in combination with other solvents like N-methyl-2-pyrrolidone), and as a chemical polisher of copper in circuit board fabrication.[3] It is also used in the textiles industry as a dye carrier in aramid fabrics.[2]
