From MS1 to Structure: A Van Krevelen–DBE–Aromaticity‐Based Framework for Annotating Specialized Metabolites via High‐Resolution Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 24, 30 December 2025.
ABSTRACT Rationale Classifying specialized metabolites in untargeted metabolomics remains a major challenge, particularly when relying solely on high‐resolution mass spectrometry (HRMS) data at the MS1 level. Traditional approaches using Van Krevelen diagrams often lack sufficient resolution to distinguish structurally similar metabolite classes ...
