2,2-Diphenoxy-propan-1,3-diol, also known as bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C21H22O4. It is a colorless, viscous liquid that is widely used as a component in the production of epoxy resins, which are essential for various applications such as coatings, adhesives, and composite materials. BADGE is formed by the reaction of bisphenol A with epichlorohydrin, resulting in a molecule that contains two phenolic hydroxyl groups and two epoxy groups. Due to its versatility and chemical properties, BADGE plays a significant role in the manufacturing of durable and high-performance materials. However, concerns have been raised about its potential health and environmental impacts, leading to increased scrutiny and regulations on its use.
The CAS Registry Mumber 4525-72-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,2 and 5 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4525-72: (6*4)+(5*5)+(4*2)+(3*5)+(2*7)+(1*2)=88 88 % 10 = 8 So 4525-72-8 is a valid CAS Registry Number.
