Two Spectrophotometric procedures are presented for the determination of two commonly used H2-receptor antagonists, nizatidine (I) and ranitidine hydrochloride (II). The methods are based mainly on charge transfer complexation reaction of these drugs with either p-chloranilic acid (rho-CA) or 2

Pentachlorophenol is the most toxic and recalcitrant chlorophenol because both aspects are directly proportional to the halogenation degree. Biological and abiotic pentachlorophenol degradation generates p-chloranil, which in neutral to lightly alkaline environmental conditions is hydrolyzed to chloranilic acid that present
The crystal structures in two solid phases, i.e. phase II stable between 146 and 253 K and phase IV below 136 K, of the title compound [phenazine-chloranilic acid (1/1), C12H8N2.C6H2Cl2O4, in phase II, and phenazinium hydrogen chloranilate, C12H9N2+.C6HCl2O4-, in phase

Two simple, rapid and sensitive spectrophotometric methods have been proposed for the determination of lisinopril in pure form and pharmaceutical formulations. The methods are based on the charge transfer complexation reaction of the drug with 7,7,8,8,tetracyanoquinodimethane (TCNQ) and p-chloranilic acid

The charge transfer interactions of Azithromycin and 7,7,8,8-tetracyanoquinodimethane (TCNQ) or chloranilic acid (CL) were investigated by spectrophotometry. The apparent molar absorptivity of TCNQ complex is 2.7 x 10(4) L x mol(-1) x cm(-1) at 743 nm, and 5.0 x 10(4)
