2-Hydroxyterephthalic acid(CAS: 636-94-2)

2-Hydroxyterephthalic acid is a dicarboxylic acid with the formula C9H8O4. It is a white crystalline solid with a pungent odor. It is an important intermediate in the production of polyethylene terephthalate (PET) and is used in the synthesis of various organic compounds and dyes.

2-Hydroxyterephthalic acid is primarily used in the production of polyester fibers and films, as well as in the synthesis of other organic compounds and dyes. It is also used in the pharmaceutical industry for the synthesis of certain drugs and intermediates.

2-Hydroxyterephthalic acid is generally considered safe when handled properly. However, it can irritate the eyes and skin, and inhalation may cause respiratory irritation. Proper protective measures, such as gloves, goggles, and a fume hood, should be used during handling. It is important to follow all safety guidelines provided by the manufacturer.

2-Hydroxyterephthalic acid should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in tightly sealed containers to prevent moisture absorption. The storage temperature should be maintained below 30°C to avoid degradation. Good air circulation is also recommended to prevent the formation of potentially explosive conditions.
