Diagnostic Fragmentation Pathways for Identification of Phthalate Metabolites in Nontargeted Analysis Studies

Prioritized candidate molecular ions in the pooled urine spiking Level-0 (Table S1) prioritized candidate molecular ions in the pooled urine spiking Level-I (Table S2), prioritized candidate molecular ions in the pooled urine spiking Level-II (Table S3), and TIC and EICs of m/z 121.0295 from the DIA data of the pooled urine sample spiked with 100 ppb of 24 metabolite standards at a collision energy of 0, 10, 20, and 40 V, respectively (Figure S1)
