What is mandelic acid?
1. DL-Mandelic acid is also known as bitter almond acidor alpha-hydroxyphenylacetic acid. Appearance: white crystalline powder, melting point range 118.0 ~ 121.0 °C. DL-mandelic acid is toxic, harmful to skin contact and ingestion.
2. Because of its strong antibacterial effect, it can be directly used orally for the treatment of urinary tract infections.
3. DL-mandelic acid has chiral molecules and is an important chiral drug intermediate and fine chemical production. It can be used not only for the synthesis of vasodilator ring mandelic acid, urinary tract infection anti-inflammatory drug DL-mandelic acid urotropine and town.
4. In 2012, China’s DL-mandelic acid consumption was about 250 tons. At present, the demand for DL-mandelic acid in the international market is growing at an average annual rate of about 10%.
5. DL-mandelic acid and its derivatives have a wide range of applications in organic synthesis.
1) If it is in medicine, it is an important intermediate for urinary tract fungicide – urotropine mandelic acid and peripheral vasodilator – cyclomanganate;
2) In the dye industry, it is also an important intermediate for the excellent heterocyclic disperse dye, benzoquinone difuranone.
Mandelic acidapplication
1. In the pharmaceutical industry, it can be used as an intermediate for cefotaxazole, vasodilator ring mandelate, eye drops oxybenzazole, pimoline, etc., and can also be used as a preservative.
2. Application areas:
1) Food: used in dairy foods, succulent foods, baked goods, pasta, seasonings, etc.
2) Medicine: health food, filler, pharmaceutical raw materials, etc.
3) Industrial manufacturing: petroleum, manufacturing, agricultural products, batteries, precision castings, etc.
