N-methylimide carbonyldichloride, also known as N-methylformimidoyl chloride or N-methylformimidoyl dichloride, is an organic compound with the chemical formula C2H3Cl2NO. It is a colorless liquid that is soluble in organic solvents and is used as a reagent in organic synthesis. N-methylimide carbonyldichloride is formed by the reaction of formamide with phosphorus oxychloride, resulting in the formation of an N-methylimide intermediate, which is then further reacted with additional phosphorus oxychloride to produce the carbonyldichloride. N-methylimide carbonyldichloride is a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its ability to act as a source of the formimidoyl group in chemical reactions. It is also known for its reactivity and can be used in the preparation of amides, esters, and other nitrogen-containing compounds.
The CAS Registry Mumber 5652-90-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 2 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5652-90: (6*5)+(5*6)+(4*5)+(3*2)+(2*9)+(1*0)=104 104 % 10 = 4 So 5652-90-4 is a valid CAS Registry Number.
