17556-69-3 Usage
General Description
[(E)-Phenylazo]methane, also known as azobenzene, is a synthetic organic compound with the chemical formula C12H10N2. It is a red-orange crystalline solid that is commonly used as a synthetic dye and in the production of polymeric materials. Azobenzene has a unique molecular structure consisting of two benzene rings linked by an azo group (N=N), giving it the ability to undergo reversible thermal and photochemical isomerization. This property makes it valuable in the development of molecular switches and materials with photoresponsive behavior. Azobenzene is also utilized in liquid crystal displays, optical storage media, and as a photosensitive compound in photodynamic therapy for cancer treatment. However, it is important to handle azobenzene with caution due to its toxicity and potential environmental hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 17556-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,5 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17556-69:
(7*1)+(6*7)+(5*5)+(4*5)+(3*6)+(2*6)+(1*9)=133
133 % 10 = 3
So 17556-69-3 is a valid CAS Registry Number.

Investigations on the stability of l-methyl-2-phenylacetohydrazide
Bresser,Weber
, p. 470 - 476 (2007/10/03)
l-Methyl-2-phenylacetohydrazide (1), a degradation product of dipyrone, is hydrolytically stable. In contrast it is oxidized into several products like 3a/3b, 4 and 5a/5b. The composition of the reaction mixture depends on the oxidation conditions (ferricyanide; hydrogenperoxide with/without peroxidase; pH 5-9) and was determined by capillary column gaschromatography.
