Product Information

• Name: 5-Hydroxyisophthalic acid
• Brand: Biosynth
• Description: 5-Hydroxyisophthalic acid is a dicarboxylic acid that has one hydroxyl group. It is an odorless, colorless solid that is soluble in water and ether. 5-Hydroxyisophthalic acid has been found to be a good thermal expansion agent for polypropylene and polyethylene, due to its intermolecular hydrogen bonding ability. This compound also has the ability to form diphenyl ethers with carboxylates, which are used as stabilizers in PVC. 5-Hydoxyisophthalic acid is not very reactive and can be used as a neutral pH stabilizer in alkaline solutions. Hydrogen bonds between 5-hydroxyisophthalic acid molecules allow it to form complexes with sodium salts, such as sodium thiosulfate or sodium nitrite. The coordination geometry of the molecule also allows for hydrogen bonding interactions with other neutral molecules, such as p-hydroxybenzoic acid
