How do I calculate the E-factor?

You can use the `get_environmental_impact` tool. Provide the reaction equation, the target product, and optionally the mass of solvents used to get the E-factor.

Does this account for catalysts?

Yes, the `get_environmental_impact` tool allows you to specify a `catalystRecoveryRate` to account for any unrecovered catalyst in the waste mass.

What is the difference between atom economy and E-factor?

Atom economy is a theoretical measure of how many reactant atoms end up in the product, while E-factor is a practical measure of total waste generated, including solvents.

This MCP server provides tools to evaluate the environmental impact and efficiency of chemical reactions. Use get_atom_economy to find the theoretical efficiency of a reaction, get_waste_metrics to determine the mass of byproducts, and get_environmental_impact to calculate the E-factor including solvents and catalyst recovery. You can also use analyze_reaction_efficiency for a high-level comparison of theoretical versus practical impact.
