Chemical classification is essential in the world of chemistry. Chemistry deals with countless compounds, and classification systems group them based on properties, structures, and functions, aiding research and organization. Proper classification helps identify and communicate chemical hazards, ensuring the safety of workers, consumers, and the environment. Categories facilitate research by grouping similar compounds, aiding in the discovery of new materials and pharmaceuticals. Governments use chemical classification to establish rules for the handling and disposal of hazardous substances. The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is widely adopted globally, standardizing chemical classification and labeling practices. Machine learning and AI assist in more efficient compound prediction and classification. ChemBlink provides the following 15 categories for its chemicals to help visitors navigate the world of chemistry.
