Molecular structure analysis of the chlorhexidine salts
Journal of Molecular Structure, 2023Novel organic salts comprising of chlorhexidine di-cation (CHX) with perchlorate H2CHX(ClO4)2·2H2O (CHXPC) and hydrogen citrate H2CHX(C6H6O7).H2O (CHXHC) were prepared, and their crystal structures studied. Despite extensive applications of chlorhexidine as an antimicrobial agent, CHXPC and CHXHC are amongst just a few reported crystal structures ...

Structure, Solubility, Screening, and Synthesis of Molecular Salts
Journal of Pharmaceutical Sciences, 2007The preparation of molecular salts as potential delivery vehicles for pharmaceutically active compounds is more common than current appreciation of the phenomena governing the solubility and isolation of salts suggests. In addition, it would appear that there are no reported measurements on a large enough data set for a serious structure-property ...

Molecular Adaptation to High Salt
2014This chapter presents the insights into adaptation provided by the study of the four genomes of extreme halophiles sequenced to date. The focus then shifts to molecular adaptation of halophilic proteins, defined as proteins isolated from extreme halophiles. Different aspects concerning solvation, stabilization of the folded and associated assemblies of

Crystal structures of mirtazapine molecular salts
CrystEngComm, 2011A few molecular salts of the anti-depressant drug R/S-Mirtazapine with organic carboxylic acids, its HCl salt, and Mirtazapine hemihydrate were crystallized and characterized by X-ray diffraction, IR and Raman spectroscopy, and thermal analysis. Whereas Mirtazapine base sublimed above ambient conditions its molecular salts do not show any sublimation ...

Molecular modelling of organic superconducting salts
AIP Conference Proceedings, 1999We have undertaken a detailed computational study of the organic superconducting charge transfer BEDT-TTF salts. The salts have wide ranging physical properties which are derived primarily from the packing of the donor-radical cations. Electronic structure calculations have been performed at the molecular and periodic level using Density Functional ...

Molecular weight distribution of graham salt
Journal of Polymer Science, 1961AbstractA method is described for determining the molecular weight distribution of Graham salt (sodium polyphosphate) by fractional precipitation with acetone. The method differs from that of Van Wazer4 in the following respects. (1) The use of smaller samples permits the fractionation to be performed in less time with consequent less hydrolytic ...

Molecular reorientation in pyrene hexafluoroarsenate salts
The European Physical Journal B - Condensed Matter, 2002The quasi-one dimensional pyrene (PY) organic conductor (PY)7(PY)4(AsF6)4 . 4CH2Cl2shows parallel as well as 60° rotated PY radical cations in its stacks, but crystallizes in two different modifications I and II. One of the seven intra-stack pyrene molecules is susceptible to a reorientation by 60°, that is stable already at room temperature for ...

Spontaneous Molecular Bromine Production in Sea‐Salt Aerosols
Angewandte Chemie International EditionAbstractBromine chemistry is responsible for the catalytic ozone destruction in the atmosphere. The heterogeneous reactions of sea‐salt aerosols are the main abiotic sources of reactive bromine in the atmosphere. Here, we present a novel mechanism for the activation of bromide ions (Br−) by O2 and H2O in the absence of additional oxidants.
