Three simple and sensitive visible spectrophotometric methods (A-C) for the determination of Ethacridine Lactate in pure samples and pharmaceutical formulations are described in the present study. They are based on the formation of colored species by treating with P-Dimethylaminocinnamaldehyde ( PDAC) reagent (Method A, lmax 600 nm) or Methyl orange (MO) reagent (Method B, lmax 420 nm) or Bathophenanthroline (BPL) reagent in presence of Ferric chloride (Method C, lmax 600 nm). These methods were extended to the analysis of pharmaceutical preparations and results are compared with the reference method (USP).
