It is a derivative of propionic acid, featuring two chlorine atoms attached to the alpha carbon, a hydroxyl group on the beta carbon, and a p-tolyl (4-methylphenyl) group also on the beta carbon. This organic compound is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, particularly as an intermediate in the production of certain herbicides and other chemical products. Its specific structure and functional groups make it a versatile building block in organic chemistry, although its use and handling require careful consideration due to its potential reactivity and toxicity.
The CAS Registry Mumber 20527-02-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,2 and 7 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 20527-02: (7*2)+(6*0)+(5*5)+(4*2)+(3*7)+(2*0)+(1*2)=70 70 % 10 = 0 So 20527-02-0 is a valid CAS Registry Number.
