ChemFileBrowser is a win32 free sotfware for chemistry designed to visualize and works with SDFile (MDL® format) to exchange and analyse information associated with chemical structure. It includes descriptors calculation like TPSA, molecular weight, HBd, HBa, Balaban, Randic, Wiener index etc. Functions : - navigate forward and backward through an SDF - introduce SDI file (SDF File index) to map directly SDF File - add and edit field name - export selected compounds - export SDF with selected fields - rename structure with a field value - export data as *.csv file - copy to clipboard (compatible with IsisDraw, ChemDraw, ViewerPro and others) - bookmark coumpounds manager - split, merge SDF - Grid view with Structure display as chemistry column - descriptors calculation : TPSA, Hydrogen Bond donor and acceptor number, molecular weight
