Amberlite XAD 8 is a highly cross-linked, nonionic, macroporous styrene-divinylbenzene copolymer resin used for adsorption and extraction purposes. It is characterized by its high surface area, large pore volume, and excellent chemical and thermal stability, making it suitable for a wide range of applications, including the separation and purification of organic compounds, preconcentration of trace elements, and removal of impurities in various industries such as pharmaceuticals, food processing, and environmental analysis. Amberlite XAD 8 is known for its ability to selectively adsorb specific compounds based on their polarity and molecular size, and it can be easily regenerated for repeated use, making it a versatile and cost-effective choice for many applications.
The CAS Registry Mumber 11104-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,1,0 and 4 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 11104-40: (7*1)+(6*1)+(5*1)+(4*0)+(3*4)+(2*4)+(1*0)=38 38 % 10 = 8 So 11104-40-8 is a valid CAS Registry Number.
