Reagent table & reaction scale calculator

Scale reactions from a base amount and generate a reagent table with eq/mol%/ppm ratios, masses, and volumes for lab-ready prep.

ppm is treated as molar ratio relative to the base (eq x 1,000,000), not mg/L.

How to use (3 steps)

  1. Enter the base compound and choose how you know its amount (mmol, mass, or solution).
  2. Add reagents and set each ratio as equiv, mol%, ppm, or a fixed amount.
  3. 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 lets you lock a reagent amount and back-calculate eq. Tip: type THF, DCM, Et3N, or DIPEA to auto-fill MW/density.

Solvent (optional)

Results

This table summarizes mmol, mass, and volume for each line based on the base reference.

How it is calculated

FAQ

What does this reagent table calculator output?

It converts equiv, mol%, or ppm ratios into mmol plus mass (g) and volume (mL) for each reagent and builds a clean reagent table you can copy, export, or share.

How are ppm and mol% defined here?

ppm is treated as a molar ratio relative to the base (eq x 1,000,000). mol% is eq x 100. Solution ppm in mg/L is not used in this tool.
