| titleOfInvention | Crystalline dihydrochloride of cephalosporin derivative and a method for preparation thereof |
| abstract | The crystalline dihydrochloride of a specific ncephalosporin derivative is stable to heat and retains its nantibacterial activity even after storage over long periods at high ntemperature. The crystalline dihydrochloride can be obtained by nremoving protective groups from the cephalosporin derivative wherein nthe amino group and carboxy groups are protected and then ncrystallizing the cephalosporin derivative from a hydrochloric acid naqueous solution. The crystalline dihydrochloride is useful for npharmaceutical preparations. |
