Spectrophotometric Determination of Cefixime Trihydrate in Pharmaceutical Formulations Based on Ion-Pair Reaction with Bromophenol Blue
Cefixime trihydrate is a broad spectrum cephalosporin antibiotic, effective against gram-positive and gram-negative bacterial infections. Simple and rapid method has been developed for the determination of cefixime trihydrate in bulk and pharmaceutical formulations. This method was based on the formation of bluish-green ion-pair complex of cefixime trihydrate with bromophenol blue in dimethyl s...
متن کاملReversible luminescent reaction of amines with copper(I) cyanide.
Copper(i) cyanide exposed to various liquid or vapor-phase amines (L) at ambient temperature produces a variety of visible photoluminescence colors via reversible formation of amine adducts. The adducts show phase matches to authentic (CuCN)L(n), n = 0.75-2.0, produced by heating CuCN with liquid amine.
متن کاملReversible luminescent reaction of amines with copper(I) cyanidew
One of the significant on-going challenges in chemistry is the specific and convenient detection of compounds of interest in the environment. Detection of volatile organic compounds (VOCs) via chemical ‘‘sniffing’’ requires an interaction between the VOC and a detector substrate, resulting in a measurable change. Crystal inclusion of VOCs into various d and d metal complexes has been found to a...
