2,2′-Azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt

Description:
2,2′-Azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, commonly referred to as ABTS, is a synthetic organic compound widely used in biochemical assays, particularly for measuring antioxidant activity. It is characterized by its stable radical form, which exhibits a distinctive blue-green color when oxidized. This compound is soluble in water and has a relatively high molecular weight. ABTS is often utilized in spectrophotometric assays due to its ability to undergo a color change in response to redox reactions, making it a valuable tool in various analytical applications, including enzyme activity assays and the evaluation of antioxidant capacity in food and biological samples. The diammonium salt form enhances its solubility and stability in aqueous solutions. Additionally, ABTS is non-toxic and has a low environmental impact, which makes it suitable for use in laboratory settings. Its versatility and reliability in providing quantitative results have made it a standard reagent in many research and industrial applications.
