BondCraft: Advanced Chemical Structure Editor

A professional biophysical tool for drawing molecules, calculating stereochemistry, and generating isomeric SMILES.

Chemical Engine Capabilities

  • Stereochemistry (Cahn-Ingold-Prelog): Implements full CIP Priority Rules to assign (R) and (S) configurations. Handles recursive comparisons for complex cyclic systems like Adamantane.
  • Smart Validation: Real-time Octet Rule validation and Formal Charge calculation. Detects expanded octets for Sulfur/Phosphorus automatically.
  • SMILES Generation: Generates canonical isomeric SMILES including chiral tags (@/@@) and directional bonds for database interoperability.

Latest Updates

Current Version 0.1.4 - Enhanced CDXML import and CDXML export with native ChemDraw compatibility, amino acids and nucleic acids structure templates, precise bounding box calculations, and updated citation formats.
