Spectrophotometric determination of tiopronin using its catalytic reaction between sodium 1,2-naphthoquinone-4-sulfonate and hydroxyl ion.
A novel and simple spectrophotometric method for the determination of tiopronin with sodium 1,2-naphthoquinone-4-sulfonate (NQS) is established in this paper. The detailed mechanism is proposed and discussed. It is based on the fact that tiopronin can catalyze the reaction between sodium 1,2-naphthoquinone-4-sulfonate and hydroxyl ion to form 2-hydroxy-1,4-naphthoquinone in a buffer solution of...
متن کاملSodium Polyethylene Sulfonate
This investigation was undertaken in view of the interest lately aroused in the association of plasma lipids with atherosclerosis. Observations on the antilipemic and anticoagulant activities in man of sodium polyethylene sulfonate, a new drug with heparin-like properties, are presented. Alteration of the serum lipoprotein patterns of these patients observed during the course of the drug admini...
متن کاملSpectrophotometric determination of ceterizine hydrochloride with Alizarin Red S.
A simple, rapid and sensitive spectrophotometric method has been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and its pharmaceutical preparations. This method is based on the ion-pair complex reaction between CTZH and Alizarin Red S in Clarks-Lubs buffer. The chromogen being extractable with chloroform, could be measured quantitatively at 440 nm. All variables were st...
متن کاملSodium polystyrene sulfonate (Kayexalate) aspiration
In this short report we illustrate a case of extensive sodium polystyrene sulfonate (SPS) aspiration as an immediate cause of death in a terminally ill patient. SPS is a cation exchange resin utilized to decrease potassium levels in patients with renal failure. When administered rectally in conjunction with sorbitol, colonic necrosis and perforation have been documented. On the other hand, oral...
متن کاملSodium quercetin-8-sulfonate trihydrate
The organic anion of the title compound, {[Na(C(15)H(9)O(10)S)(H(2)O)(2)]·H(2)O}(n) {systematic name: poly[[diaqua-[μ-2-(3,4-dihy-droxy-phen-yl)-3,5,7-trihy-droxy-4-oxo-4H-chromene-8-sulfon-ato]-sodium] monohydrate]}, has a nearly planar structure. The Na atom is six-coordinated by O atoms, two from water mol-ecules and four from the anion. The dihedral angle between the ring systems in the ani...
