What’s New in ACD/Name™ Version 2025

Japanese Language Support

• You can now generate IUPAC names for structures in Japanese, bringing the total number of supported languages to 22

English: 3-methoxy-4-methyl-5-phenoxybenzoic acid
Japanese: 3-メトキシ-4-メチル-5-フェノキシ安息香酸

Improved IUPAC Naming for Cyclic Peptides and Acyclic Heterones

• You can now generate IUPAC names for cyclic peptides with internal amido groups and disulfide bridges

Improved Support for π-Complex Search in Spectrus DB

• Variations in structure designation of π-complexes like ferrocenes are now recognized so they can be searched as one in Spectrus DB

ACD/Dictionary Expanded

• We added 1700 structures and 13,000 names to Dictionary, including common reagents and catalysts

Include Stereoconfiguration in SMILES and InChI

• You can now include stereoconfiguration for 3D structures in SMILES, and sequence representations of peptides in InChI

CAS SciFinderⁿ Search Reinstated

• You can search structures and other data in SciFinderⁿ from ChemSketch

Copy/Paste to Common Drawing Applications

• You can now copy/paste data from ChemSketch to EPAM Ketcher and ChemAxon Marvin web applications and vice versa
