5-phenoxycarbonylamino-[1,2,3]thiadiazole-4-carboxylic acid tert-butyl ester is a complex organic compound with the molecular formula C13H14N2O4S. It is a derivative of [1,2,3]thiadiazole, a five-membered heterocyclic ring containing sulfur, nitrogen, and carbon atoms. The compound features a phenoxycarbonylamino group at the 5-position, which is connected to a tert-butyl ester group at the 4-carboxylic acid position. This chemical is known for its potential applications in pharmaceuticals and agrochemicals, particularly as a building block for the synthesis of various biologically active molecules. Its stability and reactivity can be influenced by the presence of the tert-butyl group, which can protect the carboxylic acid functionality during chemical transformations.
The CAS Registry Mumber 6439-94-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,3 and 9 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 6439-94: (6*6)+(5*4)+(4*3)+(3*9)+(2*9)+(1*4)=117 117 % 10 = 7 So 6439-94-7 is a valid CAS Registry Number.
