α-Isocyano-p-tolylessigsaeureethylester, also known as ethyl α-isocyanato-p-toluate, is an organic compound with the chemical formula C10H9NO2. It is a colorless to pale yellow liquid that is soluble in organic solvents. α-Isocyano-p-tolylessigsaeureethylester is characterized by the presence of an isocyanate group (-NCO) attached to a p-tolyl group, which is a methyl-substituted phenyl ring. Ethyl α-isocyanato-p-toluate is used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. It is also employed in the production of polyurethane foams and coatings due to its reactivity with hydroxyl groups. Handling α-Isocyano-p-tolylessigsaeureethylester requires caution, as it is toxic and can cause irritation to the skin, eyes, and respiratory system.
The CAS Registry Mumber 39533-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,3 and 3 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 39533-34: (7*3)+(6*9)+(5*5)+(4*3)+(3*3)+(2*3)+(1*4)=131 131 % 10 = 1 So 39533-34-1 is a valid CAS Registry Number.
