It is a derivative of phenylhydrazine, featuring a phenylthiocarbonyl group attached to the nitrogen atom. PTCD is a white crystalline solid that is soluble in organic solvents. N-(Phenylthio-carbonyl)-N,N'-diphenylhydrazid is primarily used as a reagent in organic synthesis, particularly for the detection and determination of aldehydes and ketones. It reacts with these carbonyl compounds to form a colored complex, which can be analyzed spectrophotometrically. PTCD is also known for its potential applications in the development of chemosensors and as a building block in the synthesis of more complex molecules.
The CAS Registry Mumber 4910-33-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,1 and 0 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4910-33: (6*4)+(5*9)+(4*1)+(3*0)+(2*3)+(1*3)=82 82 % 10 = 2 So 4910-33-2 is a valid CAS Registry Number.
