Metallic Corrosion in Non-Aqueous Media

titrimetriC aSSay of liSinopril in aqueouS and non-aqueouS media

Four simple titrimetric procedures are described for the determination of lisinopril (LNP) in bulk and in pharmaceuticals based on the neutralization of basic-amino and acidic carboxylic acid groups present in LNP. Method A is based on the neutralization of basic amino groups using perchloric acid as titrant in anhydrous acetic acid medium. Method B, method C and method D are based on neutraliz...

Filamentous bacteriophage stability in non-aqueous media.

BACKGROUND Filamentous bacteriophage are used as general cloning vectors as well as phage display vectors in order to study ligand-receptor interactions. Exposure to biphasic chloroform-water interface leads to specific contraction of phage, to non-infective I- or S-forms. RESULTS Upon exposure, phage were inactivated (non-infective) at methanol, ethanol and 1-propanol concentrations inversel...
