| titleOfInvention |
Crystal form of dimaleate salt of tyrosine kinase inhibitor and preparation method thereof |
| abstract |
The present invention relates to a crystalline dimeric form of a tyrosine kinase inhibitor and a corresponding preparation method. More specifically, the present invention relates to a crystalline form IV of dimetalate of an epidermal growth factor inhibitor (EGFR) and a corresponding preparation method. The crystalline form IV exhibits good chemical stability and crystalline form stability and may be better used in clinical treatment. |
