How to use (3 steps)
- Enter the base compound and choose how you know its amount (mmol, mass, or solution).
- Add reagents and set each ratio as equiv, mol%, ppm, or a fixed amount.
- Copy the reagent table, export CSV/TSV, or share the URL.
Quick examples
Base (reference)
Reagents
Equiv, mol%, and ppm are relative to the base. Fixed amount locks a reagent amount and back-calculates eq. Tip: type THF, DCM, Et3N, or DIPEA to auto-fill MW and density.
Solvent (optional)
Results
This table summarizes mmol, mass, and volume for each line based on the base reference.
| # | Name | Role | MW | Purity | Eq | mmol | Mass | Volume | Notes |

How it's calculated
Use this page when one base scale controls the whole recipe
This reagent table is for translating equivalents, mol%, ppm, densities, and stock concentrations into one shareable prep sheet. Switch to Limiting Reagent & Yield when stoichiometric bottlenecks matter first, open Catalyst Loading for quick loading conversion, and use Solution Preparation Recipes when the task is stock or dilution prep rather than a reaction table.
- Lock the base amount and purity first so every downstream row scales consistently.
- Check liquid density and stock concentration fields before trusting volume outputs.
- Use the copied TSV or Markdown only after the displayed calculation log matches your assumptions.
FAQ
What does this reagent table calculator output?
It converts equiv, mol%, or ppm ratios into mmol, mass (g), and volume (mL) for each reagent. Then it builds a reagent table you can copy, export, or share.
How are ppm and mol% defined here?
Here, ppm is a molar ratio relative to the base (eq x 1,000,000). mol% is eq x 100. This tool does not use solution ppm in mg/L.
When should I enter density or stock concentration?
Enter density when a reagent is dosed by volume but specified by mass or mmol. Enter stock concentration when a line is supplied from solution instead of neat material. If both are blank, the tool assumes the line is weighed directly.
How does purity affect weighed mass?
Purity adjusts the weighed amount upward so the active reagent amount matches the requested mmol or ratio. Check whether a supplier lists purity, assay, hydrate, or solution strength before copying the table.
Can I trust the exported CSV or TSV directly?
Use the export for bench planning only after you confirm the calculation log, molecular weights, purity settings, density, stock units, and base amount. The file mirrors the visible table, so incorrect inputs carry into CSV and TSV.
