How do I identify the limiting reagent?

You can use the `analyze_reaction_composition` tool by providing the balanced chemical equation and the molar amounts of each reactant.

Can this tool account for side reactions?

Yes, the `calculate_actual_and_percent_yield` tool includes an optional parameter to account for reactant loss due to secondary processes.

What is atom economy?

Atom economy is a measure of how many atoms from the reactants end up in the desired product, which can be calculated using `calculate_atom_economy`.

More Details Connect to Claude

This MCP server provides a suite of precision stoichiometry tools for chemical analysis. It allows AI agents to identify limiting reagents using analyze_reaction_composition, determine maximum possible product amounts with calculate_theoretical_yield, evaluate reaction efficiency via calculate_actual_and_percent_yield, and assess mass usage efficiency through calculate_atom_economy. It is designed to handle balanced chemical equations and account for side reaction impacts.
