Dimethyl-malonyl bromide, also known as bromo-dimethylmalonic acid, is an organic compound with the chemical formula C5H7BrO4. It is a derivative of malonic acid, where the hydrogen atoms are replaced by methyl groups, and a bromine atom is attached to the carbonyl carbon. This colorless liquid is a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is used in the preparation of complex molecules, such as antibiotics and other bioactive compounds, due to its ability to serve as a building block in organic synthesis. The compound is typically synthesized through the bromination of dimethyl malonate, and its reactivity can be attributed to the presence of the bromine atom, which can participate in various chemical reactions, such as nucleophilic substitution and elimination reactions.
The CAS Registry Mumber 5659-97-2 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 9 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5659-97: (6*5)+(5*6)+(4*5)+(3*9)+(2*9)+(1*7)=132 132 % 10 = 2 So 5659-97-2 is a valid CAS Registry Number.
