Bis-phenoxymethyl ether, also known as bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C21H24O4. 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 with epichlorohydrin, resulting in a molecule that contains two phenolic groups and two epoxy groups. Due to its versatility and chemical stability, BADGE-based epoxy resins are highly valued in the manufacturing industry. However, concerns have been raised about the potential health and environmental impacts of bisphenol A, which may lead to a reevaluation of its use in certain applications.
The CAS Registry Mumber 3807-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,0 and 7 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3807-05: (6*3)+(5*8)+(4*0)+(3*7)+(2*0)+(1*5)=84 84 % 10 = 4 So 3807-05-4 is a valid CAS Registry Number.
