α-Phenyl-β-hydroxytosylhydrazon, also known as α-phenyl-β-hydroxytosylhydrazone, is a chemical compound with the molecular formula C14H16N2O2S. It is a derivative of phenylhydrazine, where a tosyl group (tosylate) is attached to the β-hydroxyl group. α-Phenyl-β-hydroxytosylhydrazon is often used as a protecting group in organic synthesis, particularly for the protection of aldehydes and ketones. The tosyl group can be selectively removed under mild conditions, making it a valuable tool for controlling the reactivity of functional groups in complex molecules. Its structure and properties make it a versatile intermediate in the synthesis of various pharmaceuticals and other organic compounds.
The CAS Registry Mumber 60417-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,4,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 60417-91: (7*6)+(6*0)+(5*4)+(4*1)+(3*7)+(2*9)+(1*1)=106 106 % 10 = 6 So 60417-91-6 is a valid CAS Registry Number.
