Potassium hydrogen phthalate - Wikipedia
网页Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid. KHP is slightly acidic, and it is often used as a primary standard for acid–base titrations because it is solid and air-stable ...

Potassium hydrogen phthalate BioXtra, = 99.95 877-24-7
网页Potassium hydrogen phthalate (KHP) is a semi-organic salt that is a member of the alkali acid phthalate series. KHP crystals are useful in devices because of their electro-optical properties. It usually acts as a model compound due to its well-developed surface pattern on the (010) face that can be easily observed by optical microscopy.
