4-methyl-2-(methyl-nitroso-amino)-thiazole-5-carboxylic acid ethyl ester is a complex organic compound with the molecular formula C8H11N3O3S. It is characterized by a thiazole ring, which is a five-membered aromatic ring containing sulfur and nitrogen. The compound features a methyl group at the 4-position, a nitroso-amino group attached to the 2-position, and a carboxylic acid group at the 5-position, which is further esterified with an ethyl group. This chemical structure endows the compound with specific reactivity and properties, making it a potential candidate for various applications in chemical research and pharmaceutical development. However, due to the presence of a nitroso group, it may exhibit certain reactivity and toxicity, necessitating careful handling and consideration of its safety profile.
The CAS Registry Mumber 3161-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,6 and 1 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3161-71: (6*3)+(5*1)+(4*6)+(3*1)+(2*7)+(1*1)=65 65 % 10 = 5 So 3161-71-5 is a valid CAS Registry Number.
