α,γ-Dimethylallylmagnesium bromide, also known as DMAM, is an organomagnesium compound with the chemical formula C7H13BrMg. It is a colorless, highly reactive, and pyrophoric liquid, which means it can ignite spontaneously upon contact with air. DMAM is commonly used as a Grignard reagent in organic synthesis, particularly for the preparation of complex organic molecules. It is synthesized by reacting α,γ-dimethylallyl bromide with magnesium metal in an ether solvent, such as diethyl ether or tetrahydrofuran. Due to its high reactivity, it is essential to handle DMAM under an inert atmosphere, such as nitrogen or argon, and to use appropriate safety precautions when working with it. The compound is widely used in the pharmaceutical and chemical industries for the synthesis of various organic compounds, including natural products, pharmaceuticals, and polymers.
The CAS Registry Mumber 6832-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,3 and 2 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 6832-11: (6*6)+(5*8)+(4*3)+(3*2)+(2*1)+(1*1)=97 97 % 10 = 7 So 6832-11-7 is a valid CAS Registry Number.
