These rules were adopted by IUPAC for naming standards and fully described in the Blue books. While flawed, they have seen many revisions over the decades and were clarified by the work of Paulina Mata. Just follow this link and try ChemDoodle for free.The CIP rules have long been the standard for describing configurations of stereochemical features in a molecule.

Select your molecule and from the menu 'Structure -> Chemical Suppliers'.Ī web page will open with the requested search result. This feature will allow you to plan synthesis much more efficiently. Just draw your chemical structures, select your molecule and go in the menu 'Structure -> Chemical Suppliers'. Retrieve the chemical structure from the ChemExper Chemical Directory directly within chemDoodle. Search for example by name for 'Cyclosporin A' and retrieve the structure for further processing. You don't feel like drawing a complex molecule ? Just retrieve it. Search by molecular formula, name and retrieve directly the corresponding information. For example if you are looking for isobutyryl chloride you may enter 'Me2CHCOCl' to retrieve all the corresponding information for products having as molecular formula C 4H 7ClO.

and this is probably the faster way to retrieve a molecule. For molecular formula you may enter groups like Me, Ts, Pro, Ala, etc. Through MolGrabber, the ChemDoodle database widget for searching online databases and accessing pre-drawn chemical figures and chemical properties, you can enter a name, molecular formula or structure and retrieve the corresponding information present in the ChemExper Chemical Directory. This can be used to retrieve information like chemical structure directly from ChemDoodle using MolGrabber or to find chemical suppliers. Moreover, starting with the recent ChemDoodle release (v 3.1), it is now possible to search directly the ChemExper Chemical Directory from within the program. ChemDoodle works on all operating systems, has one of the largest feature sets in the industry, has the most customizable graphics, pastes scalable vector graphics into Microsoft Office, iWork and OpenOffice (among others), and can read and write all popular chemical formats. ChemDoodle is the chemical drawing tool of choice for ChemExper and is the recommended tool for ChemExper users.
