CRYSTALLINE POLYMORPHIC FORMS OF MONOSODIUM N-[8-(2- HYDROXYBENZOYL)AMINO]CAPRYLATE N-[8-(2-)]

摘要

The present invention relates to crystalline polymorphic forms of monosodium N-[8-(2-hydroxybenzoyl)amino]caprylate (“SNAC”), including two hydrates, a methanol solvate, and an ethanol solvate, of SNAC. More specifically, the present invention provide six polymorphic forms of SNAC (hereafter referred to as Forms I-VI). The present invention also provides an amorphous form of SNAC.
