Webpage Viewer lets you see any web page with chemical structures highlighted in the original page. Recognized formats are IUPAC names, common names, InChI and SMILES identifiers. A chemical table of contents is organized at the top of the page with the 2D structure image of all recognized chemical structures.

To get started type or paste the URL of a web page, or pick an example from below.

Properties Viewer displays stucture based predictions for any chemical structure. Available properties include: partitioning and protonation coefficients, names and identifiers, prediction of isomerism and tautomerism, as well as charge distribution and Huckel analysis, prediction of hydrogen bonding properties and web page sources and similar structures from the chemicalize.org database.

To get started, type or paste an identifier of a chemical structure, upload a chemical structure file or draw one using an embedded drawing applet, or pick an example from below.

Chemical Search lets you perform substructure, similarity or full structure searches on the chemicalize.org structure database and find web page sources and associated structures of the results. This database includes 240000 structures identified by 370000 names on 365000 web pages visited by chemicalize.org users.

To get started, type or paste an identifier of a chemical structure, upload a chemical structure file or draw one using an embedded drawing applet, or pick an example from below.

Web Search is a combined text and chemical search engine. With it you can find chemical structures on the internet and you can search for molecules in context. Chemical structures found on the search result web pages are displayed as 2D structure images so you can choose the best result.

To get started, input a chemical structure or text search keywords or both, or pick an example from below.

Document Viewer lets you see PDF documents with chemical structures highlighted in the original pages. Recognized formats are IUPAC names, common names, InChI and SMILES identifiers. A chemical table of contents is organized at the top of the page with the 2D structure image of all recognized chemical structures.

To get started, paste the link of a PDF file or upload a PDF document, or pick an example from below. Please mind the copyright information of PDF documents when uploading!
