Chloroacetic acid (3,4-dimethylphenyl ester) is an organic compound with the chemical formula C9H9ClO2. It is an ester derivative of chloroacetic acid, where the hydroxyl group of the acid is replaced by a 3,4-dimethylphenyl group. chloro-acetic acid-(3,4-dimethyl-phenyl ester) is characterized by its aromatic structure, with two methyl groups attached to the phenyl ring at the 3rd and 4th carbon positions, and a chloroacetyl group esterified to the hydroxyl group of the phenol. It is a colorless to pale yellow liquid with a distinct aromatic odor. Chloroacetic acid (3,4-dimethylphenyl ester) is used in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its reactive ester and chloroacetyl groups, which can participate in a range of chemical reactions, including nucleophilic substitutions and ester hydrolyses.
The CAS Registry Mumber 1440-67-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 0 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1440-67: (6*1)+(5*4)+(4*4)+(3*0)+(2*6)+(1*7)=61 61 % 10 = 1 So 1440-67-1 is a valid CAS Registry Number.
