摘要:
Crystal forms of sulfonylurea compound and method for producing the same. It has been found that a sulfonylurea compound of Formula (1): has two types of crystal polymorphisms and four types of pseudo crystal polymorphisms. A production method of each crystal form of the sulfonylurea compound of Formula (1) through recrystallization or solvate has been also found. In addition, a suspension of a composition containing the crystal that is improved in storage stability is provided.
