Flow Injection Chemiluminescence Determination of Amino Acids by Oxidation with N-Bromosuccinimide.

Flow injection chemiluminescence determination of amino acids by oxidation with N-bromosuccinimide.

Flow injection chemiluminescence determination of N-bromosuccinimide and N-chlorosuccinimide.

N-bromosuccinimide-fluorescein based sensitive flow-injection chemiluminescence determination of phenformin.

A novel and highly sensitive method for the determination of phenformin over the range of 6 x 10(-9) - 1 x 10(-5) g ml(-1) in pharmaceutical formulations with flow-injection chemiluminescence (CL) detection is proposed. The method is based on the CL produced during the oxidation of N-bromosuccinimide (NBS) in an alkaline medium in the presence of fluorescein as an effective energy transfer agen...

Spectrophotometric determination of olanzapine by its oxidation with N-bromosuccinimide and cerium(IV)sulfate.

Three simple spectrophotometric methods have been described for the assay of olanzapine in its pure and pharmaceutical formulations. The direct method (A) is based on the drug oxidation with excess of N-bromosuccinimide in acidic medium and the two indirect methods (B and C) are based on the oxidation of the drug with excess of N-bromosuccinimide and cerium(IV)sulfate, followed by the reaction ...

The Decarboxylation of Amino Acids, Proteins, and Peptides by N-bromosuccinimide

One of the most widely used methods for the determination of amino acids is the ninhydrin technique perfected by Van Slyke and his coworkers (1). This permits the measurement of amino acid concentration either calorimetrically or by the volume of carbon dioxide released during the reaction. The measurement of carbon dioxide by the Van Slyke manometric apparatus is capable of great precision but...
