Build one comparison set
Load a guided lesson or search by name, alias, CAS, FEMA, JECFA, FLAVIS or family. Duplicate molecules are blocked automatically.
Fastest start — guided lesson
A lesson may contain two to six molecules. The six-slot limit prevents accidental overload.
Build your own six
Choose the destination slot, then search. A result replaces only that slot; duplicates are blocked.
Type at least two characters, then click a result. Enter chooses the highlighted result.
Tip: click “Replace in this slot” on any slot card to aim the search there.
Paste a list of up to six chemicals
Nothing is replaced until you review the preview and choose “Use matched set.”
