The Crystal Structure and Absolute Configuration of 2 ' - Deoxycytidine Hydrochloride
2'-Deoxycytidine hydrochloride (C9H14N3Q4Cl) was crystallized from water as monoclinic needles, space group P21, with a=6-561, b= 17·659, c=5·125 A, P= 108·08° and two molecules per cell. The crystal structure has been determined by a three-dimensional X-ray diffraction analysis. A complete hemisphere of data (positive and negative values of both hand k) was collected with a General Electric XR...
متن کاملThe Crystal Structure of Terramycin Hydrochloride.
The problem of determining the arrangements of atoms in crystals directly from X-ray diffraction data has engaged the attention of crystallographers for some time, and a number of approaches to this general problem have been presented. We have been especially interested in the approach which makes use of imageseeking functions in solving the Patterson synthesis,' which, in turn, is based entire...
متن کاملCrystal structure of ciprofloxacin hydrochloride 1.34-hydrate.
Ciprofloxacin belongs to a family of quinolone antibacterial agents. The crystal structure of ciprofloxacin hydrochloride 1,34-hydrate was determined. Most of the bond lengths and angles of the ciprofloxacin cation are very similar to those of ciprofloxacin hexahydrate, which appears in the zwitterionic form. The exceptions are the carbon-oxygen bond distances in the carboxylic group, since in ...
متن کاملValidated Colorimetric Assay of Clonidine Hydrochloride from Pharmaceutical Preparations
Clonidine hydrochloride is an antihypertensive agent used for migraine prophylaxis, attention deficit hyperactivity disorder, menopausal flushing and Tourette syndrome. The quantity of the active substance in pharmaceutical preparations must be within specific limits, in agreement with the respective label claim. Therefore, the aim of this study was to establish the conditions for two spectroph...
