N,N'-diphenyl-C-benzoyl-formazan, also known as DPCBF, is a chemical compound with the molecular formula C23H17N3O2. It is a formazan derivative, characterized by its conjugated π-electron system and the presence of a benzoyl group. DPCBF is often used as a spectroscopic probe for the detection of reactive oxygen species, particularly singlet oxygen, due to its ability to undergo a photochemical reaction that results in a significant change in its absorption spectrum. This property makes it a valuable tool in various research fields, including photochemistry, biochemistry, and materials science, where the generation and detection of reactive oxygen species are of interest.
The CAS Registry Mumber 2032-96-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,3 and 2 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2032-96: (6*2)+(5*0)+(4*3)+(3*2)+(2*9)+(1*6)=54 54 % 10 = 4 So 2032-96-4 is a valid CAS Registry Number.
