Bis-(4,4'-diphenyl-benzhydrylidene)-hydrazine, also known as Michler's ketone, is a chemical compound with the molecular formula C38H30N2. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and ether. bis-(4,4'-diphenyl-benzhydrylidene)-hydrazine is derived from the condensation of benzhydrol with hydrazine, resulting in a symmetrical molecule with two benzhydryl groups connected by a central hydrazine bridge. Michler's ketone is primarily used as a chemical intermediate in the synthesis of various dyes, pigments, and pharmaceuticals. It is also employed as a fluorescent brightening agent in the textile industry and as a reagent in analytical chemistry for the detection of certain metal ions. Due to its potential health and environmental risks, handling and disposal of Michler's ketone must be done with proper precautions and in accordance with safety regulations.

1184-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1184-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.Calculate Digit Verification of CAS Registry Number 1184-33:
(6*1)+(5*1)+(4*8)+(3*4)+(2*3)+(1*3)=64
64 % 10 = 4
So 1184-33-4 is a valid CAS Registry Number.
