Table

Paste a list and build the table.

What the table holds

Each line is matched to the catalogue: names and CAS numbers by search, SMILES by structure. The table gives the formula, molar mass, density, melting and boiling point, flash point, pKa and the GHS signal word with its pictograms, each linked to the compound page. Copy pastes a tab-separated table into a spreadsheet or a notebook; CSV downloads the same. The list stays in the address bar, so the link can be shared.

Reaction scaleFix the amount of one reagent and get masses, volumes and moles for everything else from equivalents and density. StoichiometryBalance the equation, enter what you have, and see the limiting reagent, theoretical yield and excess. Molar massMolar mass, exact mass, elemental composition and the isotope pattern for any formula or structure. Equation balancerBalance any equation, including ions and redox half-reactions, with exact integer coefficients.
