ChemPencil is a fast, native Mac scientific 2D chemical structure editor for chemists, students, and educators
ChemPencil is a fast, native Mac scientific 2D chemical structure editor for chemists, students, and educators. Sketch molecules the way you think about them, work with real chemistry data — not just pretty pictures — and move files freely between the tools you and your collaborators already use. DRAWING • Single, double, and triple bonds with left/right/center alignment • Wedge, hashed, wavy, bold, and dashed stereo bonds • Ring palette: 3- to 8-membered rings, benzene, cyclopentadiene, cyclohexane chairs • Reaction arrows (forward, equilibrium, retrosynthetic) with conditions above and below the shaft • Curved mechanism arrows (double-barbed and fishhook) • Brackets (square, round, curly), text labels, formal charges, isotopes, highlights, and element coloring • "Magic Hotkeys" for fast atom and bond editing without switching tools CHEMISTRY, NOT JUST GRAPHICS • Implicit hydrogens with live valence and over-valence checking • Calculated properties: formula, MW, monoisotopic mass, TPSA, cLogP, H-bond donors/acceptors, rotatable bonds, degree of unsaturation, formal charge • Simulated isotopic mass spectrum • Nicknames library (Me, Et, Ph, Bn, Ac, Ts, OMe, NO₂, CF₃, CO₂H…) with one-click set / expand • Clean Up Structure, Auto-Orient, Equalize Bond Angles NOMENCLATURE & SEARCH • Generate IUPAC name from structure • Structure from IUPAC name • Find and Replace substructure, query atoms, query bonds, atom lists, SMARTS REACTIONS • Reaction conditions editor • Atom-to-atom mapping • Reaction stoichiometry panel INTEROPERABILITY • Read and write native .chemp, MOL, SDF, RXN, RDF, SMILES, CDXML • Copy InChI, InChIKey, SMILES, MOLfile, CDXML, SMARTS • Export PDF (vector), SVG, PNG, TIFF • Rich clipboard: paste vector + raster + native into any app • QuickLook thumbnails and previews in Finder 3D VIEWER • Interactive SceneKit 3D window for any 2D structure DESIGNED FOR MAC • Universal binary (Apple silicon + Intel) • Sandboxed and hardened, no telemetry, no account required • AppleScript automation • Multiple document windows, page setup, and printing Includes ready-made sample documents (aspirin synthesis, caffeine, amino acids, and more) to explore right after you launch.
