Phthalic acid-d4 is a potential health hazard that is used in the synthesis of azelaic acid. The anthropogenic nature of this chemical has been confirmed by its stable isotope. Phthalic acid-d4 can be identified using its Raman spectra, which are different from those of other phthalic acids. This chemical is a white solid with a melting point of about 68 degrees Celsius and a density of 1.09 grams per cubic centimeter. It has an odor threshold of 0.5 parts per million, which is well below the human sense detection threshold for most people.br>Phthalic acid-d4's primary physical property is that it is soluble in tetroxide and dilute sulfuric acid, but not water at room temperature (20 degrees Celsius). It also forms an insoluble residue when diluted with water at room temperature.br>Phthalic Acid-D4 can be found in polyethylene terephthalate plastics,
