| titleOfInvention | L-aspartic acid amlodipine crystal form and preparation method and application thereof |
| abstract | The invention discloses an L-aspartic acid amlodipine crystal form which is characterized in that Cu-Kalpha radiation is used for X-ray diffraction of the crystal form, and X-ray diffraction expressed by a 2 theta angle has peaks at the following positions: 9.3 +/-0.2 degrees, 9.9 +/-0.2 degrees, 12.2 +/-0.2 degrees, 12.9 +/-0.2 degrees, 19.2 +/-0.2 degrees, 19.8 +/-0.2 degrees, 22.2 +/-0.2 degrees, 24.2 +/-0.2 degrees and 26.6 +/-0.2 degrees, and the L-aspartic acid amlodipine crystal form prepared by the method has better quality and stability and is beneficial to long-term storage. |
