    摘要: A stable crystal of a salt of N—[(R)-1-{(S)-2-hydroxy-2-phenylpropylamino}propan-2-yl]isoquinoline-6-sulfonamide may have desirable properties for a pharmaceutical drug substance, and more specifically N—[(R)-1-{(S)-2-hydroxy-2-phenylpropylamino}propan-2-yl]isoquinoline-6-sulfonamide dihydrochloride anhydride. A crystal of the anhydride may have characteristic peaks at 2θ angles of 6.8±0.1°, 10.0±0.1°, 12.7±0.1°, 14.6±0.1°, 14.8±0.1°, 16.2±0.1°, 17.4±0.1°, 17.8±0.1°, 19.5±0.1°, 20.0±0.1°, 21.6±0.1°, 24.7±0.1°, 25.5±0.1°, 25.8±0.1°, 29.8±0.1°, 39.5±0.1°, and/or 44.9±0.1° in powder X-ray diffraction spectrum.
