4,4'-dioxo-4,4'-(4,4'-methanediyl-di-phenyl)-di-butyric acid, also known as bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C23H22O6. It is a colorless, viscous liquid that is widely used in the production of epoxy resins, which are essential components in various applications such as coatings, adhesives, and composite materials. BADGE is formed by the reaction of bisphenol A (BPA) with epichlorohydrin, resulting in a diglycidyl ether structure. 4,4'-dioxo-4,4'-(4,4'-methanediyl-di-phenyl)-di-butyric acid is known for its excellent adhesion properties, chemical resistance, and thermal stability, making it a valuable additive in the manufacturing of epoxy-based products. However, due to concerns over the potential health risks associated with BPA, there has been increased scrutiny and research into the safety of BADGE and its derivatives.
The CAS Registry Mumber 4374-75-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 4 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4374-75: (6*4)+(5*3)+(4*7)+(3*4)+(2*7)+(1*5)=98 98 % 10 = 8 So 4374-75-8 is a valid CAS Registry Number.
