Undecane, 1-(methoxymethoxy)-, also known as 1-(Methoxymethoxy)undecane or Methoxymethyl undecyl ether, is a colorless liquid with a molecular formula of C13H28O2 and a molecular weight of 216.36 g/mol. It is an ether derivative of undecane, where a methoxymethyl group (-OCH2O-) is attached to the terminal carbon atom of the undecane chain. This chemical is primarily used as a solvent, intermediate in the synthesis of other organic compounds, and in the production of surfactants and detergents. It is characterized by its low toxicity, high boiling point (around 250°C), and good solubility in organic solvents. Due to its chemical structure, it exhibits low reactivity and is relatively stable under normal conditions.
The CAS Registry Mumber 79128-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,2 and 8 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 79128-66: (7*7)+(6*9)+(5*1)+(4*2)+(3*8)+(2*6)+(1*6)=158 158 % 10 = 8 So 79128-66-8 is a valid CAS Registry Number.
