Synthetic peptide reconstitution benchmark

A small, inspectable set of deterministic cases for checking mass, concentration, unit conversion and target volume calculations. Every row can be read without an instrument, a sample or a hidden dependency.

What this fixture checks

Mass concentration

Rows cover mg and µg inputs with targets expressed as mg/mL, µg/mL or µg/µL.

Molar concentration

Three rows require an explicit molecular mass before a target in mM can be converted to mg/mL.

Regression checks

The expected volume is fixed for each row, so a validator can catch unit mistakes without guessing.

volume (mL) = mass (mg) ÷ concentration (mg/mL)

Scope: These are synthetic calculation cases. They do not describe a vial, batch, purity result, identity test, clinical dose or administration protocol.

Try a calculation

Use the same arithmetic contract as the benchmark. For an mM target, enter the molecular mass in daltons.

2.000 mL 10 mg ÷ 5 mg/mL

Reproduce it locally

The repository contains the CSV, schema, dataset card and validator. From a clean checkout:

npm ci
npm run benchmark:reconstitution

The validator checks every expected volume and prints the SHA-256 of the input file. The benchmark is deliberately small so a reviewer can inspect each row.
