How we scored it

Whole molecule C6H6N2O3 is a synthetic nitro-aminophenol; aromatic ring from phenol/aniline petrochemicals, no natural fragment. 0/154=0.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from
