1,1-Bis-<4-(3-hydroxy-3-methyl-but-1-inyl)-phenyl>-aethan, also known as Bisphenol A diglycidyl ether (BADGE), is a chemical compound that belongs to the class of epoxy resins. It is synthesized by reacting bisphenol A (BPA) with epichlorohydrin, resulting in a colorless to pale yellow liquid. BADGE is widely used as a curing agent in the production of epoxy resins, which are employed in various applications such as coatings, adhesives, and composite materials. The compound is known for its excellent adhesion properties, chemical resistance, and mechanical strength. However, concerns have been raised regarding the potential health and environmental impacts of BADGE, as it can release bisphenol A, a hormone-disrupting chemical, during its use and disposal. As a result, there is ongoing research and development of alternative materials to replace BADGE in certain applications.
The CAS Registry Mumber 1566-48-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,6 and 6 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1566-48: (6*1)+(5*5)+(4*6)+(3*6)+(2*4)+(1*8)=89 89 % 10 = 9 So 1566-48-9 is a valid CAS Registry Number.
