α,α'-Di-(4-methylanilino)-dibenzylketon, also known as Michler's ketone, is an organic compound with the chemical formula C23H22N2. It is a derivative of benzophenone, where two 4-methylaniline groups are attached to the carbonyl group. This yellow crystalline solid is widely used as a chemical intermediate, particularly in the synthesis of various dyes and pigments, such as azo dyes. Michler's ketone is also employed as a fluorescence brightening agent in the textile industry and as a reagent in analytical chemistry. Due to its photoreactive properties, it has been studied for potential applications in photodynamic therapy. However, it is important to note that Michler's ketone is a suspected carcinogen and should be handled with care.

32897-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32897-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,8,9 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 32897-91:
(7*3)+(6*2)+(5*8)+(4*9)+(3*7)+(2*9)+(1*1)=149
149 % 10 = 9
So 32897-91-9 is a valid CAS Registry Number.
