Abstract:The purpose of this study was to develop and standardize a protocol for the novel use of a benzopyrone derivative, namely 4-hydroxycoumarin (4-HC), for the estimation of cotinine to identify tobacco consumers using Konig’s reaction. 4-HC was soluble in 2-propanol and 1-butanol at a concentration of 100 mg/mL and 80 mg/mL, respectively. Cotinine was estimated by Konig’s reaction using three different formats in which the physical nature of primarily two reagents, potassium thiocyanate and Chloramine-T, was vari… Show more
