ChemDraw Pro Suite v23.1.1.3 Design a variety of molecular and chemical structures
ChemDraw Professional Suite v23.1: The Chemist’s Essential Upgrade for Precision Molecular Design
What Is ChemDraw Professional Suite?
- ChemDraw Professional: Advanced 2D structure drawing with NMR prediction, name-to-structure conversion, and analytical chemistry tools.
- Chem3D: 3D molecular modeling, energy minimization, and conformational analysis.
- ChemFinder: Chemical database management and substructure searching.
- HELM Editor: Specialized tools for drawing complex biopolymers using the Hierarchical Editing Language for Macromolecules.
Key Highlights of ChemDraw Professional Suite v23.1
Enhanced HELM Capabilities for Biopolymer Research
- Refined Cursor Display: A clearer visual indicator shows exactly where monomers will be inserted, reducing errors when building complex sequences.
- Cleaner Canvas Visualization: Expanded monomer labels are now concealed by default, decluttering the workspace and improving readability of large constructs.
- Intelligent Selection Behavior: Double-clicking an atom or bond now selects the entire monomer; a subsequent double-click selects the full sequence—accelerating editing workflows.
- GenBank FASTA Support: Directly paste DNA or RNA sequences from GenBank FASTA format, with header information automatically converted to annotations.
Improved Annotation Management
- Bulk Deletion: A new “Delete All” option allows rapid removal of custom annotations from objects or entire documents.
- Smarter Paste Operations: When pasting content, existing annotations are now respected and preserved, maintaining document integrity during collaborative editing.
Streamlined Property Calculations
- Optimized Property Updates: When editing large structures with the Chemical Properties window open, calculations are now queued to minimize interface lag.
- Foundation for RDKit Integration: Preparatory improvements support the transition to RDKit-powered LogP and Molar Refractivity calculations in subsequent releases.
Enhanced Python and Automation Support
- ChemScript Compatibility: Continued support for Python 3.9.x, 3.10.x, and forward-looking compatibility with 3.13.x enables flexible automation of drawing, analysis, and reporting tasks.

Workflow Impact: Before and After v23.1
Revvity Signals is delighted to announce the newest release of ChemDraw v23.1, with updates included in ChemDraw Prime, Professional and Signals ChemDraw. The latest minor release of ChemDraw Desktop introduces improvements in the areas of HELM and document level annotations.
Key highlights for ChemDraw v23.1:
- HELM Improvements:
- A refined cursor display now offers a clearer view of monomer insertion points, facilitating easier drawing and editing of biopolymers.
- The visualization of expanded monomers has been optimized by concealing their labels, decluttering the canvas.
- The selection behavior of a monomer has been refined; a double-click on an atom or bond now selects the entire monomer, while a subsequent double-click selects the entire sequence.
- Added support for pasting GenBank FASTA DNA/RNA sequences.
- Annotation Handling:
- Improved document annotations with a new ‘Delete All’ option and smarter paste operations that respect existing annotations.
- Various bugs addressed.
