On the Physicochemical Properties of Pyridohelicenes

Chemistry – A European Journal, 2013
AbstractA comprehensive study on the physicochemical properties of a series of mono‐ and diaza[5]helicenes as well as mono‐ and diaza[6]helicenes is reported. Through the use of both computational and experimental methods, these helically chiral pyridohelicenes with the nitrogen atom(s) in various positions are characterised according to their ...

Physicochemical Properties of Iodixanol

Acta Radiologica, 1995
Iodixanol, the radiopaque in Visipaque, is a new nonionic, dimeric roentgen contrast medium for intravascualr use. Compared to aqueous solutions of nonionic monomers, which have higher osmolality than blood, aqueous solutions of iodixanol have a lower osmolality due to dimeric structure of the molecule.

The physicochemical properties of digoxin

Journal of Pharmaceutical and Biomedical Analysis, 1985
In a study of variations in the physicochemical properties of digoxin powder from several commercial sources, recrystallizations of digoxin were performed under several conditions. Polymorphs were not obtained whereas a pure amorphous form was formed under certain conditions.

Physicochemical properties of enrofloxacin

Journal of Pharmaceutical and Biomedical Analysis, 1997
The physicochemical properties of enrofloxacin, a fluoroquinolone that inhibits the activity of bacterial DNA gyrase, are described. Its spectral, solubility and related physicochemical characteristics are discussed. The dissociation behaviour of enrofloxacin was examined by UV spectrophotometry at 25 degrees C in a series of buffers ranging from pH 1 ...

Physicochemical Properties of Dodecylammonium Picrate

Journal of Colloid and Interface Science, 2000
A novel surfactant, dodecylammonium picrate (DDAP), was synthesized and its crystal structure was determined by X-ray diffraction analysis. DDAP's physicochemical properties were examined by spectral (infrared and nuclear magnetic resonance), thermal, microscopic, and conductometric studies.

Determination of physicochemical properties of tetrabromobisphenol A

Environmental Toxicology and Chemistry, 2008
Abstract Aqueous solubility (Sw), 1-octanol/water partition coefficient (KOW), and vapor pressure of the nonionic form of 2,2′,6,6′-tetrabromo-4,4′-isopropylidenediphenol (tetrabromobisphenol A or TBBP-A) were measured. From this, enthalpies of solution and vaporization were estimated.
