A simple and sensitive spectrophotometric method was described for the determination of Meropenem in pure and in pharmaceutical formulations. 2,3 dichloro 5,6 dicyano 1,4 benzoquinone(DDQ)has been used for determination of meropenem by formation of charge transfer complex measured at 345 nm.Beer᾽s law is obeyed in the concentration range of (0.625-12.5µg/ml) The molar absorptivity (2.3889×104)l.mol1-.cm1-,Sandellʹs sensitivity index is 0.0161µg.cm2-,The method is precise (relative standard deviation RSD% is better than ±3.32%) and accurate (relative error in the range of -0.97 to-0.60%) depending on the concentration level.
The method was applied succefully to the assay of Meropenem in pharmaceutical preparation in the form of injection.
