Calculated interactions of a nitro group with aromatic rings of crystalline picryl bromide.
Several crystalline polymorphs have been discovered for picryl bromide. Among the several forces that control the formation of such polymorphs are the interactions among the nitro groups and phenyl rings of those crystals. Although there are >300 structures to be found in the Cambridge Structural Database displaying the nitro-phenyl interaction, nonetheless this interesting, and apparently impo...
متن کاملNew polymorphs of curcumin.
Two new crystalline polymorphs and an amorphous phase of the active curcuminoid ingredient in turmeric are reported. Curcumin polymorph 2 has higher dissolution rate and better solubility than the known polymorph 1.
متن کاملTwo polymorphs of 1,8-dichloroanthracene.
A second, monoclinic, polymorph of the title compound, C(14)H(8)Cl(2), has been found. In addition to the structure of this monoclinic form, the structure of the previously described orthorhombic form [Desvergne, Chekpo & Bouas-Laurent (1978). J. Chem. Soc. Perkin Trans. 2, pp. 84-87; Benites, Maverick & Fronczek (1996). Acta Cryst. C52, 647-648] has been redetermined at low temperature and usi...
متن کاملRocuronium Bromide Versus Vecuronium Bromide
BACKGROUND: Rocuronium Bromide is a newer, low potency nondepolarising neuromuscular blocking agent. It is proven to be five to seven times less potent than vecuronium.The aim of the present study was to evaluate the effectiveness of 2ED95 (2 times effective dose 95) dose (0.6mg/kg) of rocuronium with regard to onset time, the intubating conditions and the duration of action and to compare it w...
متن کاملPolymorphs and hydrates of acyclovir.
Acyclovir (ACV) has been commonly used as an antiviral for decades. Although the crystal structure of the commercial form, a 3:2 ACV/water solvate, has been known since 1980s, investigation into the structure of anhydrous ACV has been limited. Here, we report the characterization of four anhydrous forms of ACV and a new hydrate in addition to the known hydrate. Two of the anhydrous forms appear...
