Statistics are calculated from public compounds and public experimental records only. Compound-distribution panels count unique compounds; NMR-parameter tracks show individual experimental records.

Annual literature and data evolution
Distinct publications, compounds reported, first compound appearances, and public NMR records per publication year.
Structural subgroup coverage
Unique compounds per structural subset.
Low-frequency subgroup cutoff—
cut-off breakdown:hideshow
Groups containing no more than the integer compound cutoff corresponding to the selected share are combined into one “Below threshold” group. At 0%, no grouping occurs; the maximum is 10% of compounds in the selected year window.subgroup omission threshold; 0% = no grouping; max.: 10%
