چکیده
In the title water-solvated salt, C(21)H(22)P(+)·Br(-)·H(2)O, the ionic components are linked by short C-H⋯Br contacts along the a-axis direction. The two half occupied water mol-ecules are connected to each other by strong O-H⋯O hydrogen bonds and they are also linked to the bromide anion by short O-H⋯Br contacts.

Identification of Polymorphic Forms of Active Pharmaceutical Ingredient in Low-Concentration Dry Powder Formulations by Synchrotron X-Ray Powder Diffraction
BACKGROUND The identification of different (pseudo) polymorphs of an active pharmaceutical ingredient in dry powder formulations is of importance during development and entire product lifecycle, e.g., quality control. Whereas determination of polymorphic differences of pure substances is rather easy, in dry powder formulations, it is generally difficult and the difficulties increase particularl...

In the crystal structure of the title compound, C(20)H(39)N(2) (+)·Br(-)·H(2)O, the 1-hexa-decyl-3-methyl-imidazolium cations are stacked along the b axis, forming channels parallel to [100] which are occupied by the bromide anions and water mol-ecules. The crystal is stabilized by O-H⋯Br, C-H⋯O and C-H⋯Br hydrogen-bonding inter-actions, generating a two-dimensional network.
متن کاملAggregation of cefprozil monohydrate
Aggregation behaviour of cefprozil monohydrate (C18H19N3O5S.H2O), an antibiotic, has been studied in presence of sodium dodecyl sulphate (SDS) and Cetyltrimethylammonium bromide (CTAB). Critical micelle concentration (CMC) of drug is determined to be 0.34 mM and is observed to decrease significantly at SDS < 2 mM. Above this concentration increase is less prominent and remains almost constant. ...
