WebFeb 9, 2024 · Stereoisomerism plays a crucial role in the science and technology of chemistry, but this is a relatively new development. Analytical and synthetic techniques have not yet advanced to the stage that allows configuration to be assigned with the same ease as other aspects of molecular structure. WebThis service works as a resolver for different chemical structure identifiers and allows one to convert a given structure identifier into another representation or structure identifier. It can help you identify and find the chemical structure if you have an identifier such as an InChIKey. You can either use
