    摘要: The present invention relates to a crystalline form of a phenyl carbamate derivative compound and a use thereof, and more particularly, to a more thermodynamically stable crystal, i.e., a Pattern 1 crystalline form, and a preparation method thereof. Amorphous and crystalline forms were prepared using various solvents, and among these, a thermodynamically stable Pattern 1 crystalline form and a pharmaceutical use of this crystalline form are provided.
