3-amino-4-methyl-2-methylimino-2,3-dihydro-thiazole-5-carboxylic acid ethyl ester is a complex organic compound with the chemical formula C8H14N2O2S. It is a derivative of thiazole, a heterocyclic compound consisting of a five-membered ring with one sulfur atom and two nitrogen atoms. The molecule features an amino group (-NH2) at the 3-position, a methyl group (-CH3) at the 4-position, and a methylimino group (-CH=N-) at the 2-position. The thiazole ring is fused to a 2,3-dihydro ring, and the molecule contains a carboxylic acid group (-COOH) at the 5-position, which is esterified with an ethyl group (-CH2CH3). 3-amino-4-methyl-2-methylimino-2,3-dihydro-thiazole-5-carboxylic acid ethyl ester is known for its potential applications in pharmaceuticals and agrochemicals, particularly as a building block for the synthesis of various biologically active molecules.
The CAS Registry Mumber 4552-26-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 2 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4552-26: (6*4)+(5*5)+(4*5)+(3*2)+(2*2)+(1*6)=85 85 % 10 = 5 So 4552-26-5 is a valid CAS Registry Number.
