N-Bromosuccinimide-Fluorescein Based Sensitive Flow-Injection Chemiluminescence Determination of Phenformin

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...

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

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

Flow injection chemiluminescence analysis for highly sensitive determination of noscapine

Noscapine is an antitussive drug and possesses potent antitumor activity. This work establishes a highly sensitive method for its determination by flow injection chemiluminescence (CL) technique. This method is based on its strong sensitizing effect on the weak CL reaction between sulfite and acidic permanganate. The mechanism for the sensitizing process is proposed on the basis of fluorescence...

Development of a sensitive flow injection-chemiluminescence detection method for the indirect determination of propranolol

A highly sensitive flow injection-chemiluminescence detection (FI-CL) method based on pyrogallol (Pg) chemiluminescent reagent (CLreagent) oxidized by periodate for the determination of propranolol is presented. The presented method is an indirect CL detection method based on the CL emission generated during the oxidation of Pg with the excess of periodate that remains after oxidation of propra...
