5-Methoxy-3,4-dihydro-2(1H)-naphthalenone oxime is a chemical compound with the molecular formula C11H13NO2. It is derived from the parent compound 2(1H)-naphthalenone, which is a type of ketone with a naphthalene ring structure. The presence of a 5-methoxy group (-OCH3) at the 5th position and a 3,4-dihydro (saturated) structure in the molecule distinguishes it from other naphthalenones. This oxime derivative is formed by the addition of a hydroxylamine (NH2OH) group to the carbonyl carbon of the ketone, resulting in the formation of a C=N bond. The compound is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its use as an intermediate in organic chemistry. Its properties, such as solubility and reactivity, can be influenced by the presence of the methoxy and oxime functional groups, making it a versatile building block in chemical synthesis.
The CAS Registry Mumber 3899-04-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,9 and 9 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3899-04: (6*3)+(5*8)+(4*9)+(3*9)+(2*0)+(1*4)=125 125 % 10 = 5 So 3899-04-5 is a valid CAS Registry Number.
