MS Reactivity

Automatic workflows for accurate prediction of reactivity and catalysis

Materials Science: Reactivity


MS Reactivity offers two highly automated modules for modeling in molecular chemistry and catalysis. The first module, Automated Reaction Workflow (AutoRXNWF), is intended for chemical reaction and reactivity optimization with quantum mechanics based on a user-defined library and a reference reaction. One example of the application of AutoRXNWF is molecular catalyst design. The second module, Nanoreactor, is intended to identify reaction products for any reaction and sort them based on thermodynamics principles. This is achieved via automated potential energy surface (PES) sampling with semiempirical metadynamics, PES refinement, and sorting based on free energies. One of the applications of Nanoreactor is the study of small molecule degradation products without any prior knowledge.


The high-throughput AutoRXNWF represents the first-ever computational workflow that can predict both a catalyst’s selectivity (regio-, chemo- and/or enantioselectivity) and turnover frequency (TOF) from quantum mechanics. The workflow offers optional conformational search and geometry pre-optimization with classical force fields and/or extended tight-binding (xTB) and runs (pseudospectral) density functional theory (DFT) at the last stage. Among various output properties, machine learning (ML) descriptors are also available on demand.

Chemical degradation is the process by which chemical substances undergo structural changes, leading to the breakdown of their molecular integrity into simpler chemical compounds. This process is at the heart of chemical failure and material lifetime, natural degradation and aging, and recycling. It unfolds through diverse mechanisms, among which thermal decomposition, photolysis, oxidation, and hydrolysis are the most prevalent. With Schrödinger’s Nanoreactor, you can effortlessly discern all potential degradation products for small molecules and categorize them based on thermodynamic principles. Simply furnish the input structure and click the run button to unlock a comprehensive analysis.
