It is a colorless liquid with a molecular weight of 102.13 g/mol. This ketone derivative is characterized by the presence of a methyl group (CH3) at the 3rd carbon, a methoxy group (OCH3) at the 1st carbon, and a carbonyl group (C=O) at the 2nd carbon. It is used as a solvent and a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its volatility and potential health risks, it is essential to handle 2-Butanone, 1-methoxy-3-methyl- with proper safety measures.
The CAS Registry Mumber 65857-35-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,5 and 7 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 65857-35: (7*6)+(6*5)+(5*8)+(4*5)+(3*7)+(2*3)+(1*5)=164 164 % 10 = 4 So 65857-35-4 is a valid CAS Registry Number.
