Pyrogallic acid  ·  1,2,3-Trihydroxybenzene
Pyrogallol is an organic compound with the formula C6H3(OH)3. It is a white water-soluble solid although samples are typically brownish because of its sensitivity toward oxygen. It is one of three isomeric benzenetriols.
deferiprone (30652-11-0)  
CP20  ·  L1 oral chelate  ·  3-hydroxy-1,2-dimethyl-4-pyridinone
Deferiprone (tradenames include Ferriprox) is a drug that chelates iron and is used to treat iron overload in thalassaemia major. It was first approved for use in treating thalassaemia major in 1994 and had been licensed for use in Europe and Asia for many years while awaiting approval in Canada and the United States. On October 14, 2011, it was approved for use in the US under the FDA’s accelerated approval program.
O-PHENYLENEDIAMINE (95-54-5)  
1,2-phenylenediamine  ·  ortho-phenylenediamine  ·  orthophenylenediamine
o-Phenylenediamine is an organic compound with the formula C6H4(NH2)2. This aromatic diamine is an important precursor to many heterocyclic compounds. It is isomeric with m-phenylenediamine and p-phenylenediamine, and is commonly referred to as OPD.
malic acid (78644-42-5, 6915-15-7, 617-48-1)  
malate  ·  malic acid, disodium salt, (S)-isomer  ·  calcium (hydroxy-1-malate) hexahydrate
Malic acid is an organic compound with the molecular formula C4H6O5. It is a dicarboxylic acid that is made by all living organisms, contributes to the pleasantly sour taste of fruits, and is used as a food additive. Malic acid has two stereoisomeric forms (L- and D-enantiomers), though only the L-isomer exists naturally.
