ChemSketch 8.0 Freeware

Quickly and easily draw molecules in a chemistry-oriented
interface with customizable toolbars.
Instantly calculate the chemical formula, molecular weight,
and percentage composition. Predict several liquid properties such
as density and refractive index.
Customize display properties, e.g., atom numbering, chemical symbols,
and valence.
Draw reactions and schematic diagrams.
Drawing of Molecular Structures
- Select atom, click, and drag to create bonds;
- "Chemical intelligence" automatically assigns hydrogens
and charges to fill valence and shows when the valence limit of bonding
has been exceeded;
- New! Wide range of special bond types - aromatic, delocalized,
undefined single and double stereo, quadruple, and several presentations
of coordination bonds;
- Draw Markush structures (generic view);
- New! Draw delocalized structures;
- Draw polymers;
- Present reactions: draw, import/export, map atom-atom
transformation (manual as well as automatic), and edit reaction conditions;
- Customize display properties, e.g., atom numbering,
chemical symbols, valence and so forth;
- Control Hydrogen position near each atom;
- View hundreds of new structures in the template window;
- Change template orientation when attaching to another
structure;
- Use the "Clean" option for the entire molecule
or user-selected fragments;
- Change a drawing's appearance to a different style
(e.g., J. Org. Chem. style) in one step;
- Paste structures drawn in other applications or import
them as a file;
- View 3D rotation; and
- Apply powerful 2D rotation and move/resize features.
Chemistry
- Draw 2D structures and obtain 3D models with the geometry optimization
button;
- Instantly display chemical formula, molecular weight, percentage
composition, and estimated macroscopic properties: molar refractivity,
refractive index, molar volume, density, parachor, and others;
- New! Expanded Periodic Table of Elements includes physical and
NMR properties and isotope composition for each element;
- Draw reactions and complex chemical schemes with manual or automatic
mapping;
- Update the internal database of fragment names and abbreviations
with your own data;
- Spell-check chemical abbreviated structures; and
Save and read widely used chemical formats (MOL, SKC, CDX, CHM,
RXN, and SK2).
