Abstract

The increasing utilization of polymeric materials, elastomeric assemblies, single-use systems, pharmaceutical packaging components, and biomedical devices has intensified concerns regarding the release of material-derived chemical entities into products and biological environments. Extractable species encompass a chemically diverse spectrum of compounds including residual monomers, catalysts, antioxidants, oligomers, plasticizers, processing aids, degradation products, and manufacturing-related impurities. Traditional extractables investigations have largely relied on targeted analytical methodologies that focus on predefined compounds, often failing to capture the full extent of chemical complexity present within modern material systems. Consequently, a paradigm shift toward comprehensive, systems-level characterization is required. This review introduces Extractomics, a novel multidisciplinary framework designed to investigate extractable species through the integration of advanced analytical chemistry, high-resolution instrumentation, cheminformatics, toxicological assessment, data science, and regulatory intelligence. Extractomics aims to establish a holistic understanding of extractable ecosystems by combining untargeted screening, molecular fingerprinting, structural elucidation, exposure modelling, and risk prioritization. Emerging technologies including high-resolution mass spectrometry, nuclear magnetic resonance spectroscopy, ion mobility spectrometry, artificial intelligence, and machine learning are discussed as enabling tools for Extractomics-based investigations. Furthermore, the review examines current regulatory expectations, methodological challenges, and future opportunities associated with the implementation of Extract-omics in pharmaceutical, biomedical, environmental, and industrial applications. The proposed framework represents a transformative approach for advancing material safety assessment and improving scientific understanding of chemical migration phenomena.
