Sodium salt or free acid?
[edit]CAS lists this CAS# (72-57-1) and name as the tetrasodium salt, but we have the free acid shown. Can someone confirm which one is the dye? Walkerma (talk) 05:20, 20 January 2009 (UTC)
Molecular mass
[edit]PubChem claim that the TB molecular weight is 960.8 g/mol, not 872.88. Please confirm and update. Akokustatal (talk) 08:45, 9 January 2020 (UTC)
- Check the chemical formula. The relative molecular mass has to be consistent with that. —DIV
