A wide range of physical constants, for instance melting point, boiling point, specific gravity, viscosity, refractive index, solubility, polymorphic forms vis-a-vis particle size, in addition to characteristic absorption features and optical rotation play a vital role in characterization of pharmaceutical chemicals and drug substances. These physical constants will be discussed briefly with typical examples as under ... [Pg.11]

With other solvents, e.g., oil of turpentine, pinewood oil, light mineral oils, resin, tar, shale or camphor oil, the density and boiling point may be determined and various other determinations made, such as the rotation, refractive index, solubility in aniline, behaviour towards fuming nitric acid. The special reactions of resin oil, pinewood oil, shale oil and camphor oil may also be applied. [Pg.316]

Properties often used by epoxy resin manufacturers to specify particular grades of resin include the epoxy content, viscosity or softening point, and color. In addition, properties such as density, vapor pressure, flash point, refractive index, solubility characteristics, and hydroxyl content are often reported. The important properties of uncured epoxy formulations with regard to most adhesive applications are... [Pg.44]

Because each member of a pair of enantiomeric molecules differs from the other only in the spatial arrangement of the ligands attached to the chiral center, their physical properties, that is, melting point, boiling point, refractive index, solubility, etc., are identical. The major difference between the isomers of an enantiomeric pair was first observed by Biot in 1815 when he noted that one form of tartaric acid rotated plane-polarized light, whereas another form did not (1).

The elongated p-sheet domains are typically stabilized in supermolecular structures by a large number of intermolecular H bonds. Such polysaccharides are typically insoluble and form highly ordered compact structures with a rather high crystallinity index solubility is increased if branches break the basic p-sheet symmetry (Fig. 3B).

Historically, the use of xanthines has been hampered by poor aqueous solubility, rapid but highly variable metabolism, and the existance of a low therapeutic index. Solubility problems were partially solved by the preparation of various salt forms, eg, aminophjlline. However, it was since recognized that the added base in aminophylline only increases solubility by increasing pH and thus does not affect the rate of absorption from the gut (65). Thus, in more recent medical practice, theophylline is commonly dispensed in anhydrous form and aminophylline is only recommended for iv administration. [Pg.440]
