About
MoldChem Tools is a free, professional-grade chemistry toolkit — 63 calculators and lookups
that run entirely in your browser.
It's built for the moment a chemist, production-floor operator, or student has a task in front of
them and needs a fast, correct answer: sizing a batch, prepping a solution, balancing a reaction,
checking a hazard rating, looking up a CAS number. Not a destination app — a utility you reach for
mid-experiment and close.
What's inside (7 categories): stoichiometry and yield, molarity, dilutions and solution prep,
pH and buffers, titration and normality, gas laws and colligative properties, spectroscopy and
chromatography, NFPA/GHS labeling and PPE/compatibility safety lookups, plus industrial tools for
electroplating, paint, fertilizer, water treatment, polymers, and more to come.
What makes it different:
Client-side and instant — calculations run in your browser with no server round-trip (except lookups through API).
Transparent and cited — methods implemented from first principles, with references, so the results are trustworthy and citable.
Printable — NFPA diamonds, GHS labels, and prep cards print clean for the cabinet or the team.
Private by design — no login, no paywall, no ads, and no tracking.
Built and maintained by MoldChem. The tools are free and will stay free (except AI features to come).
