General description

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.

Application

Potassium hydrogen phthalate has been used as a substrate to assess the permeation from the extracellular (EC) to the periplasmic (PP) side through DcaP. It has also been used as one of the polyurethane materials for the characterization of polyester triol (OH).

Features and Benefits

  • Long-term stability
  • Exhibits dielectric properties
