Magnesium, chloro(methoxymethyl)-, also known as chloromethyl methyl ether or CMME, is an organomagnesium compound with the chemical formula ClCH2OMgBr. It is a colorless, highly reactive, and moisture-sensitive liquid that is commonly used as a Grignard reagent in organic synthesis. CMME is prepared by reacting magnesium metal with bromochloromethane and methanol. It is widely used in the formation of carbon-carbon bonds, particularly in the synthesis of complex organic molecules, due to its ability to react with a variety of electrophiles, such as carbonyl compounds, to form new carbon-carbon bonds. The use of CMME as a Grignard reagent offers advantages such as increased reactivity and selectivity compared to other Grignard reagents, making it a valuable tool in the field of organic chemistry.
The CAS Registry Mumber 4279-02-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 9 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4279-02: (6*4)+(5*2)+(4*7)+(3*9)+(2*0)+(1*2)=91 91 % 10 = 1 So 4279-02-1 is a valid CAS Registry Number.
