Orphenadrinium picrate picric acid
The asymmetric unit of the title compound N,N-dimethyl-2-[(2-methyl-phen-yl)phenyl-meth-oxy]ethanaminium picrate picric acid, C(18)H(24)NO(+)·C(6)H(2)N(3)O(7) (-)·C(6)H(3)N(3)O(7), contains one orphenadrinium cation, one picrate anion and one picric acid mol-ecule. In the orphenadrine cation, the two aromatic rings form a dihedral angle of 70.30 (7)°. There is an intra-molecular O-H⋯O hydrogen ...
متن کاملDibenzo-18-crown-6–picric acid–water (1/2/3)
In the crown ether ring of the title compound, C(20)H(24)O(6)·2C(6)H(3)N(3)O(7)·3H(2)O, the O-C(H(2))-C(H(2))-O torsion angles indicate a gauche conformation of the ethyl-eneoxy units, while the C-O-C-C torsion angles indicate planarity of these segments; the dihedral angle between the two benzene rings is 44.53 (13)°. In both picric acid mol-ecules, one of the nitro groups is twisted away from...
متن کاملDevelopment of a Field Method for Quantifying Ammonium Picrate and Picric Acid in Soil and Water
Methods for the detection and quantification of ammonium picrate and picric acid in soil and water were developed. Picrate ions were extracted from water directly or from acetone extracts of soil by solid-phase, acidic, ionexchange materials. Elution from the ion exchangers was accomplished by converting the retained picrate to picric acid using strong aqueous, acid– organic solvent mixtures. T...
متن کاملBenzamide–picric acid (1/1)
In the title compound, C(7)H(7)NO·C(6)H(3)N(3)O(7), one of the nitro groups of the picric acid mol-ecule lies in the plane of the attached benzene ring [dihedral angle = 1.4 (1)°] while the other two are twisted away by 9.9 (1) and 30.3 (1)°. In the benzamide mol-ecule, the amide group is almost coplanar with the benzene ring [dihedral angle = 4.4 (1)°]. An intra-molecular O-H⋯O hydrogen bond g...
متن کاملAntibody-Conjugated Paramagnetic Nanobeads: Kinetics of Bead-Cell Binding
Specific labelling of target cell surfaces using antibody-conjugated paramagnetic nanobeads is essential for efficient magnetic cell separation. However, studies examining parameters determining the kinetics of bead-cell binding are scarce. The present study determines the binding rates for specific and unspecific binding of 150 nm paramagnetic nanobeads to highly purified target and non-target...
