APPLICATIONS
There are three isomeric compounds of trihydroxybenzene molecule structure, which all have traditional names respectively. Their names are related with the equivalent dihydroxybenzene compounds. The names of the three compounds indicate which of the hydrogens on the benzene ring portion of the molecule have been replaced by hydroxyl groups. The isomer of 1,2,3-trihydroxybenzene is called pyrogallic acid (or pyrogallol).  This compound is a poisonous acid, derived from gallic acid, and used  in the manufacturing colorants such as azo dyes and photographic developers and externally as an antimicrobial to treat certain skin diseases. Phloroglucin (or called phloroglucinol) is 1,3,5-trihydroxybenzene which presents as the genin of many glycosides, particulrally in the bark of apple and other trees. It is used in as a reagent for pentoses, pentosans, glycuronates, hydrochloric acid in gastric juice. It is an excellent bone decalcifying agent and a floral preservative. It is used in the manufacture of pharmaceuticals. The 1,2,4- isomer is hydroxyquinol (or called hydroxyhydroquinone). Trihydroxybenzenes have three hydroxyl groups in one benzene ring. They can derive numerous esters and salts. They are used as chemical intermediate to synthesis target molecules of pharmaceuticals, pesticides, stabilizer, antioxidant, colorants, perfumes, photoinitiators, and other organic compounds. Methoxylated phenol family compounds have bacteriostatic and  floral preservative properties.  They are used in pharmaceuticals and flavorings. They are used in formulating insect attractants, analgesics, biocides and antiseptics. They are also used in manufacturing stabilizers, antioxidants, and UV absorbers for plastics and rubbers.  An example of target product from 1,3,5-Trimethoxybenzene is buflomedil, a vasoactive agent which improves the symptoms of impaired blood circulation.
