Chlorantraniliprole [794]

Content Handbook P


Outline of method
The sample is dissolved in unstabilised tetrahydrofuran and subsequently diluted with the mobile phase, a mixture of acetonitrile and a buffer of 0.005 M NaH2PO4•H2O adjusted to pH 3.0 with H3PO4. The analysis is conducted via reversed phase liquid chromatography using a 3.0 μm particle, 4.6 x 150 mm Ace® 3 C18 column and UV detection at 275 nm. Alternately, a 2.6 μm particle, 4.6 x 100 mm Kinetex® C18 olumn or a 2.7 μm particle, 4.6 x 100 mm Restek Raptor® C18 column may be substituted for the AceÒ C18 column. The weight percent of chlorantraniliprole in each sample is determined by comparison of peak area or peak area ratio if an internal standard is used, versus a calibration curve prepared from the analysis of standard solutions.



The method is usable for TC, FS, WG, SC, snf MT 184 formulations.
