On March 15, 2005, Liu, Yong; Wang, Jingkang; Yin, Qiuxiang published an article.Recommanded Product: 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate The title of the article was The crystal habit of ciprofloxacin hydrochloride monohydrate crystal. And the article contained the following:
Crystals with two different habits (e.g. needle-like and plate-like) of ciprofloxacin hydrochloride monohydrate (CPFX) were prepared from aqueous solution by varied methods. These crystals were identified by various means such as scanning electron microscope (SEM), DSC, TG, and x-ray powder diffraction (XRPD). According to the anal. of crystals by DSC, TG and XRPD, it is concluded that CPFX crystals produced in cooling or dilution crystallization experiment should have the same crystal structure. Using the XRPD data, the unit cell parameters were calculated by software TREOR90. Systematic absence and statistics of reflexion indicate that CPFX crystals in this work have a high possibility of being the space group P21/c. The crystal habit transition was observed in the salting-out crystallization when 0.2M KCl solution works as precipitant. The experimental process involved the reaction of 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate(cas: 86393-32-0).Recommanded Product: 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate
