Mass transitions monitored by liquid chromatography tandem mass spectrometry
| Chemical | Transitions (m/z → m/z) |
|---|---|
| Triclocarban (TCC) | 313 → 160 |
| 13C6-TCC | 319 → 160 |
| d7-TCC | 322 → 165a |
| Triclosan (TCS) | 287 → 35 |
| 13C6-TCS | 293 → 35 |
| 13C12-TCS | 299 → 35 |
Due to overlap from the 13C6-TCC transition, the 37Cl isotope transition was used for the internal standard d7-TCC
