More Information
Summary:The present invention relates to a novel crystalline form of a benzimidazole derivative and a preparation method thereof. The novel crystalline form according to the present invention is hardly changed chemically and/or physically under a long-term photo-stressed condition, has a low hygroscopicity, and has an extremely low static-electricity-inducing capability, thus being advantageous for formulation, and due to the excellent stability of the crystal form itself, it is very useful for long-term storage ofthe compound.
