Abstract
This is out line work on the process development for the impurity detection of Isatin from synthetic occurring and several
new methods have been developed during the pursuit of this research. The article traces the evolution of various approaches and
provides a comparison for overall efficiency. UPLC method has been developed and validated for simultaneous estimation of matrix
impurity, disregards impurity; specified impurity associated undetectable impurity in pure synthetic formulations. Separation was
carried out using column Hypersil ODS C18 (250 mm x 4.6mm x 5μm particle size) in isocratic mode using mobile phase composition
pH 6.0 ammonium acetate Buffer: Acetonitrile (68:32) v/v and UV detection at 310 nm. The impurities were eluted at a flow rate
of 1.0 mL/ min. The average retention times for matrix impurity, disregards impurity, specified impurity associated undetectable
impurity were 2.86 and 3.67 min, 4.54 min respectively. The method was validated according to the ICH guidelines.
