Acetic acid, (2,4-dichlorophenoxy)-, 2,4-dichlorophenyl ester, also known as 2,4-dichlorophenoxyacetic acid (2,4-D), is a widely used synthetic auxin-type herbicide. It is an ester derivative of acetic acid, with a 2,4-dichlorophenoxy group attached to the hydroxyl group of the acetic acid molecule. 2,4-D is primarily used to control broadleaf weeds and woody plants in agricultural fields, lawns, and gardens. It works by mimicking the action of natural plant hormones, causing uncontrolled growth and eventually leading to the death of the targeted plants. The chemical structure of 2,4-D is characterized by its two chlorine atoms at the 2 and 4 positions of the phenoxy ring, which contribute to its herbicidal activity and selectivity. However, due to its potential environmental and health concerns, the use of 2,4-D has been subject to regulations and restrictions in various countries.

5253-45-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5253-45-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,5 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5253-45:
(6*5)+(5*2)+(4*5)+(3*3)+(2*4)+(1*5)=82
82 % 10 = 2
So 5253-45-2 is a valid CAS Registry Number.

The title compounds (3) have been prepared and their chemical properties studied.With iodine they give aryloxymethyl aryloxyacetates (4) through the intermediacy of aryloxyacetyl hypoiodites and α-iodoanisoles.The former are unstable but have been trapped with pyridine to give N-iodopyridinium aryloxyacetates, whereas the latter are stable and react independently with compounds (3) to afford the acetates (4).The termolysis of (3) has been studied and, besides esters (4), aryl aryloxyacetates are also formed.The mechanism of the thermolysis is briefly discussed.
