Making Claude a Chemist

Anthropic is enhancing Claude's chemistry proficiency by training it to interpret complex analytical data like NMR spectra. Recent tests demonstrate that the Opus 4.7 model performs as well as, or better than, specialized industry software when predicting how molecules react to magnetic fields. Beyond simple prediction, the AI successfully performs structure elucidation, a difficult task where it identifies unknown molecules based solely on experimental readings. This capability allows researchers to translate between various chemical representations, such as hand-drawn sketches and technical data, more efficiently than traditional tools. By automating these time-consuming analytical processes, the goal is to provide a versatile assistant that supports scientists in navigating massive chemical registries and complex synthetic workflows. While current evaluations are small in scale, they indicate that general-purpose AI is becoming a formidable tool for modern laboratory research.
