About Us

Our Mission

We built the Theoretical Yield Calculator to provide students, educators, and lab professionals with a clean, fast, and reliable tool for everyday chemistry calculations. We believe that scientific tools should be accessible, instantaneous, and respect your privacy.

What We Offer

Our tools have grown beyond simple stoichiometry. To accommodate the diverse needs of modern lab work, we now offer a comprehensive suite of tools:

• Theoretical Yield: Calculate the maximum amount of product predicted from your starting material and balanced equation.
• Percentage Yield: Compare your actual experimental yield to the theoretical maximum to determine efficiency.
• Basic Molarity: Calculate the molarity of a solution from mass, molecular weight, and volume.
• Mass from Volume: Find out exactly how much compound to weigh out to prepare a solution at a specific concentration.
• Volume from Mass: Calculate the required final solution volume when your compound mass and target concentration are known.
• Molarity from Mass: Instantly find the molarity of a solution when you dissolve a known mass into a specific volume.
• Stock Dilution: Automate the C1V1 = C2V2 formula to dilute a concentrated stock solution accurately.
• Peptide Synthesis Yield: Calculate expected mass for Solid-Phase Peptide Synthesis based on resin loading and peptide MW.
• Peptide Coupling: Calculate exact reagent amounts for single amino acids or full peptide sequences in SPPS.
• Peptide Risk Analyzer: Analyze sequence for aggregation, DKP, and aspartimide risk to optimize your synthesis.

All our calculators run entirely in your browser. This means no waiting for server responses, no accounts, and no tracking.
