Abstract
An objective of the present invention is to provide a crystal of 2-ethyl-3,7-dimethyl-6-(4-(trifluoromethoxy)phenoxy)quinoline-4-yl methyl carbonate having stable physicochemical properties. The objective is attained by a crystal of 2-ethyl-3,7-dimethyl-6-(4-(trifluoromethoxy)phenoxy)quinoline-4-yl methyl carbonate that exhibits a diffraction peak pattern shown in FIG. 1 as determined by powder X-ray diffractometry.
