International Chemical Identity

International Chemical Identity (ICI) is a standardized way to specify a chemical substance unambiguously. It uses internationally agreed identifiers like chemical names, CAS numbers, and unique codes such as InChI (International Chemical Identifier) to ensure that scientists and regulators worldwide can recognize and communicate about the same substance accurately. This helps prevent confusion, enhances safety, and facilitates sharing of chemical information across borders, research, and industry. Essentially, ICI provides a precise, universally understood label for chemicals, similar to a globally recognized address for each unique compound.
