IUPAC

A new InChI Web App has been launched, offering chemists an interactive tool for converting chemical structures, inspecting InChI identifier layers, and comparing different InChI versions in one place. The tool is free and openly available through the IUPAC InChI project's website. The announcement is being shared in cheminformatics and open science communities, where users are welcoming a convenient browser-based alternative to command-line utilities for the standard chemical identifier.

A new tool called Orthonym has been introduced that generates verified IUPAC names for chemical structures. The names are written strictly by rule following the IUPAC 2013 standard, with no machine learning or sampling involved. Each name is then independently read back using OPSIN to confirm accuracy, and the tool reports its confidence level, declining to produce a name when it is unsure. The launch is drawing attention from chemists and informatics researchers interested in reliable chemical naming.
