5-(3-chloro-anilino)-[1,2,3]thiadiazole-4-carboxylic acid ethyl ester is a complex organic compound with the chemical formula C10H9ClN2O2S. It is a derivative of [1,2,3]thiadiazole, a five-membered heterocyclic ring containing sulfur, nitrogen, and carbon atoms. The molecule features a 3-chloroaniline group attached to the thiadiazole ring, which is further esterified with an ethyl group at the carboxylic acid position. 5-(3-chloro-anilino)-[1,2,3]thiadiazole-4-carboxylic acid ethyl ester is of interest in the field of medicinal chemistry, particularly in the development of potential therapeutic agents, due to its unique structure and the presence of a chlorine atom, which can influence its reactivity and biological activity. The ethyl ester group may also play a role in the compound's solubility and metabolic properties.
The CAS Registry Mumber 2039-18-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,3 and 9 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2039-18: (6*2)+(5*0)+(4*3)+(3*9)+(2*1)+(1*8)=61 61 % 10 = 1 So 2039-18-1 is a valid CAS Registry Number.
