Online Demo - Fast 3D Structure Generation with CORINA Classic

Please draw a structure with the structure editor or enter a chemical structure as a SMILES string in the form below and press the Submit button (or just use the "L-alanine" example for demonstration). CORINA Classic will generate 3D coordinates for the given structure. A new page will be generated showing the 3D molecular model if you are using a HTML5 compatible browser.

Remarks: Enter the chemical structure as a SMILES string. This program will NOT recognize IUPAC names of compounds (or misinterpret them according to the SMILES syntax). Case matters. Element symbols without capital letters in the first character (e.g., c, n, ...) are interpreted as sp2 hybridized atom types according to the SMILES syntax.
