1,4-Naphthalenedione, 2-[(3-ethoxyphenyl)amino]-, also known as 2-(3-ethoxyphenylamino)-1,4-naphthoquinone, is an organic compound characterized by a naphthalene core with a quinone functional group at the 1,4-positions and an ethoxyphenylamine substituent at the 2-position. This chemical features a naphthalene ring system, which consists of two fused benzene rings, and a quinone moiety, which is a type of organic compound with two oxygen atoms bonded to adjacent carbon atoms in a ring. The ethoxyphenylamine group provides an additional layer of complexity, with an ethoxy (ethyl ether) functional group attached to a phenyl ring that is further connected to an amino group. 1,4-Naphthalenedione, 2-[(3-ethoxyphenyl)amino]- is of interest in various chemical and pharmaceutical applications due to its unique structure and potential reactivity.
The CAS Registry Mumber 64505-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,0 and 5 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 64505-53: (7*6)+(6*4)+(5*5)+(4*0)+(3*5)+(2*5)+(1*3)=119 119 % 10 = 9 So 64505-53-9 is a valid CAS Registry Number.
