3-ethyl-isoxazole-4,5-dione 4-[(2,3-dichloro-phenyl)-hydrazone] is a complex organic compound with the chemical formula C10H7Cl2N3O2. It is a derivative of isoxazole, a heterocyclic compound with a five-membered ring containing two oxygen atoms and one nitrogen atom. The molecule features a 3-ethyl substituent, which is an ethyl group attached to the isoxazole ring, and a 4-hydrazone group, which is formed by the reaction of the isoxazole-4,5-dione with a 2,3-dichloro-phenylhydrazine. The presence of two chlorine atoms on the phenyl ring contributes to the compound's overall structure and properties. This chemical is primarily used in research and development, particularly in the synthesis of various pharmaceuticals and agrochemicals, due to its unique reactivity and potential applications in drug design.
The CAS Registry Mumber 1627-79-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 7 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1627-79: (6*1)+(5*6)+(4*2)+(3*7)+(2*7)+(1*9)=88 88 % 10 = 8 So 1627-79-8 is a valid CAS Registry Number.
