SciFinder One of the most comprehensive indexes to the chemical literature and related science and engineering disciplines. Search millions of articles, patents, and conference proceedings and abstracts; millions of chemical substances via the CAS Registry (including many with property data and spectra); millions more of single- and multi-step reactions and preparations via CAS Reactions; and thousands of chemical supplier catalogs. Search by topic, author, chemical substance by name, registry number, or structures. From the substance record, browse the available property data, explore relevant reactions, or look for commercial suppliers. Every reaction and property data point includes a reference back to the original article or patent, or another chemical provider. Import structures from ChemDraw to run a structure/substructure or reaction search, or use the built-in editor to draw your structures or generate them with a CAS Registry Number. First-time users will need
