MetFrag combined results (top) and results for the top 3 candidates (bottom) retrieved with the MS-Ready search for C9H16ClN5. The score categories are (1st to 7th): MetFrag Fragmentation, Exact Spectral Similarity, Data Sources, Presence in NORMAN Priority list, Number of PubMed Articles, Presence in STOFF-IDENT, and Percent Active ToxCast Assays. Terbutylazine had the highest score, above propazine. Sebutylazine (which, if present, often co-elutes with terbutylazine in common NTA methods) has a lower score due to fewer metadata values (absent from NORMAN list and no ToxCast bioassay data)
