Spectrophotometric determination of atropine, pilocarpine and strychnine with chloranilic acid.
In dioxan-chloroform medium the acceptor chloranilic acid forms 1:1 molecular complexes with the alkaloids atropine, pilocarpine and strychnine, with maximum absorption at 535, 527.5 and 535 nm respectively. Conformity with Beer's law allows the use of the complexes for the assay of these drugs.
متن کاملSimultaneous spectrophotometric analysis of aliphatic amines utilizing thermochromism of charge-transfer complexes with tetrabromophenolphthalein ethyl ester.
Aliphatic amines, such as n-hexylamine (primary), di-n-hexylamine (secondary) and tri-n-hexylamine (tertiary amine), react with tetrabromophenolphthalein ethyl ester molecules (TBPEH) to form reddish or red-violet charge-transfer complexes (CT complexes) in 1,2-dichloroethane (DCE). The absorption maxima of the CT complexes with all primary amines occur at around 560 nm, with secondary amines a...

Fig. I is a rad ioautograph of the ionogram. The free phospha te b a n d has been allowed to run off the anode end of the paper. The exac t correspondence of the radioact ive bands from the three diisopropyl phosphory l -enzymes indicates tha t the hydro lysa tes contain identical pept ides of phosphoserine which are ent i re ly different from those der ived from ovalbumikx. The s t ruc ture of...
متن کاملEthyl Maltol as a New Ligand for Spectrophotometric Determination of Iron
In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...
متن کاملGlycine ethyl ester hydrochloride
In the crystal structure of the title compound, C(4)H(10)NO(2) (+)·Cl(-) (systematic name: 3-eth-oxy-3-oxopropan-1-aminium chlor-ide), there are strong inter-molecular N-H⋯Cl, C-H⋯Cl and C-H⋯O hydrogen-bonding inter-actions between the free chloride anion and the organic cation, resulting in a two-dimensional supra-molecular network in the ab plane.
