Abstract

Disclosed in the present application is a crystal polymorph of potassium N-[8-(2-hydroxybenzoyl)amino]octanoate, wherein the crystal polymorph of potassium N-[8-(2-hydroxybenzoyl)amino]octanoate is crystal Form I, and the crystal Form I has at least an X-ray powder diffraction pattern with characteristic peaks represented by 2θ° of 7.83±0.2, 26.64±0.2 and 18.89±0.2. The crystal polymorph of potassium N-[8-(2-hydroxybenzoyl)amino]octanoate provided by the present application has four crystal forms, has high solubility and strong stability, can deliver drugs more effectively, increases the permeability of the delivered drugs in the gastrointestinal tract, and is beneficial to the preparation of oral preparations, such that preventive and/or therapeutic drugs can be better delivered into the body to achieve the effect of improving the bioavailability.
