Quantity determination of Recorcinol by coupling reaction with diazotized Of 4-aminacet phenone

Development of an analytical method to determine Recorcinolcompound by coupling reaction for diazotized solution 4- aminacetphenone in the presence buffer NasHPO, (pH= 10.8) give acompound with a single azo dye salt having orange color soluble waterwith high absortivity at wave length 449 nm , early study have aperfect optimum condition was made determination. A calibrationcurve range concentration (5-75)pm taken and value ofmolar 1.5*10° L.mol'.cm™ relative standarddeviation more than 1.26% recovery 98.77% .As we natureof mole fraction method, from practical foundthat compound is 1:1(Recorcinol: 4-aminacetphenone) stability factor reach 1.4*10° L.mol’.
