Separation and determination of process-related impurities of erlotinib using reverse-phase HPLC with a photo-diode array detector.

چکیده
A simple and rapid reverse-phase high-performance liquid chromatographic (HPLC) method for the simultaneous separation and determination of erlotinib and its process-related impurities in bulk drugs has been developed. Five process-related impurities of erlotinib have been separated on an Inerstsil ODS-3V (C18) column and detected at 254 nm using a photo diode array (PDA). This HPLC method was successfully applied to the analysis of erlotinib bulk drug. The recoveries of erlotinib and process-related impurities were in the range of 92.86-106.23%, and found to be specific, precise and reliable for the determination of unreacted raw materials, intermediates in the reaction mixtures and bulk drugs.
