Simultaneous Determination of Genotoxic Impurities in Fudosteine Drugs by GC-MS.
A simple, sensitive and reliable gas chromatography mass spectrometry (GC-MS) method has been developed, optimized and validated for the simultaneous determination of 3-chloro-1-propanol (CHP), 1,3-dichloropropane (DCP), 3-chloropropylacetate (CPA) and chloropropyl hydroxypropyl ether (CHE) contents in fudosteine, using chlorobenzene as internal standard. Efficient chromatographic separations were achieved on an Agilent J&W DB-WAXetr, 30 m long with 0.32 mm i.d., 1.0 µm particle diameter column that consists of bonded and cross-linked polyethylene glycol as a stationary phase by passing helium as the carrier gas. The analytes were extracted in dichloromethane and monitored by gas chromatography electron ionization mass spectrometry (GC-EI-MS) with selective ion monitoring (SIM) mode. The performance of the method was assessed by evaluating specificity, precision (repeatability and reproducibility), sensitivity, linearity and accuracy. The limit of detection and limit of quantification established for CHP, DCP, CPA and CHE were in the range of 0.05-0.08 µg mL(-1) and 0.10-0.17 µg mL(-1), respectively. The recoveries for CHP, DCP, CPA and CHE were in the range of 92.0-101.5%. The results proved that the method is suitable for the simultaneous determination of contents of CHP, DCP, CPA and CHE in fudosteine.
