How to use (3 steps)
- Add compounds and reaction steps, including yields and recoveries.
- Choose backward (target) or forward (starting materials) mode.

FAQ
Can I use grams instead of mmol?
Yes. Set the display unit to g and provide MW to convert between mmol and grams.
What if a step has two inputs?
The planner uses equivalents to determine the limiting input and computes the expected output accordingly.
What should I do first on this page?
Start with the minimum required inputs or the first action shown near the primary button. Keep optional settings at defaults for a baseline run, then change one setting at a time so you can explain what caused each output change.
Why does this page differ from another tool?
Different pages often use different defaults, units, rounding rules, or assumptions. Align those settings before comparing outputs. If differences remain, compare each intermediate step rather than only the final number.
How reliable are the displayed values?
Values are computed in the browser and rounded for display. They are good for planning and educational checks, but for regulated or high-stakes decisions you should validate assumptions with official guidance or professional review.
