In the triprolidinium cation of the title compound {systematic name: 2-[1-(4-methyl-phen-yl)-3-(pyrrolidin-1-ium-1-yl)prop-1-en-1-yl]pyridin-1-ium bis-(2,5-dichloro-4-hy-droxy-3,6-dioxo-cyclo-hexa-1,4-dien-1-olate)-2,5-dichloro-3,6-dihy-droxy-cyclo-hexa-2,5-diene-1,4-dione-methanol-water (2/1/2/2)}, C(19)H(24)N(2) (2+)·2C(6)HCl(2)O(4) (-)·0.5C(6)H(2)Cl(2)O(4)·CH(3)OH·H(2)O, the N atoms on both ...

Chromatographic and spectrophotometric methods for the estimation of mebendazole in pharmaceutical products were developed. The flow injection method was based on oxidation by a known excess sodium hypochlorite at pH=9.5. is then reacted with chloranilic acid (CAA) to bleach out its color. absorbance CAA recorded 530 nm. fast, simple, selective, sensitive. chromatographic carried Varian C18 col...

Studies were carried out to develop a simple, rapid and accurate spectrophotometric method for the analysis of fifteen cephalosporins. The method depends on the charge-transfer complexation reaction between any of these drugs as an n-electron donor and p-chloranilic acid (p-CA) as a pi-acceptor to form a violet chromogen measured at 520 nm. Different variables affecting the reaction were studie...
