354trihydroxy

354trihydroxy is not a standard chemical name. In isolation it does not uniquely identify a molecule and may be a shorthand or a mis-typed descriptor indicating three hydroxyl (OH) groups placed at positions 3, 5, and 4 on a given parent structure. If the intent is a benzene ring bearing three hydroxyl substituents, the conventional descriptor would be something like 3,4,5-trihydroxy- with the remaining substituent specified; the well-known example in this class is 3,4,5-trihydroxybenzoic acid, commonly called gallic acid, which has a carboxyl group and three phenolic OH groups.

Gallic acid is a natural phenolic compound widely found in gall nuts, tea, wine, and various plants. It is used as an antioxidant, in cosmetics, as a flavoring or stabilizer in food processing, and as a starting material for pharmaceuticals and polymer synthesis. Other possible interpretations of 354trihydroxy include triols in sugars or polyols where three hydroxyl groups are located at carbon numbers 3, 4, and 5 in a specific sugar or polyol skeleton; without structural information, these remain speculative.

In chemistry nomenclature, providing a precise structural descriptor (such as parent scaffold and exact substituent positions) or an identifier (SMILES, InChI, or registry number) is necessary to uniquely identify a compound.
