It is a colorless liquid with a molecular weight of 230.67 g/mol. This ester is derived from acetic acid and 4-chloro-2-ethylphenol, and it is formed by the esterification reaction between the carboxylic acid group of acetic acid and the hydroxyl group of 4-chloro-2-ethylphenol. Acetic acid, (4-chloro-2-ethylphenoxy)-, ethyl ester is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of herbicides. It is important to note that due to its chemical structure, it may have potential environmental and health implications, and thus, proper handling and disposal are crucial.
The CAS Registry Mumber 2867-51-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,6 and 7 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2867-51: (6*2)+(5*8)+(4*6)+(3*7)+(2*5)+(1*1)=108 108 % 10 = 8 So 2867-51-8 is a valid CAS Registry Number.
