2-(2,4-Dichlor-phenoxy)-ethyl-dibutyl-phosphat, also known as 2,4-dichlorophenoxyethyl dibutyl phosphate, is a chemical compound with the molecular formula C16H22Cl2O4P. It is an organophosphate ester derived from 2,4-dichlorophenoxyacetic acid (2,4-D) and dibutyl phosphite. <2-(2,4-Dichlor-phenoxy)-ethyl>-dibutyl-phosphat is primarily used as a herbicide, specifically as an ester form of 2,4-D, which is a widely used selective herbicide for controlling broadleaf weeds and grasses in various agricultural settings. The dibutyl phosphate ester form enhances the herbicide's solubility and absorption by plants, making it more effective in controlling unwanted vegetation. It is important to note that the use of such chemicals requires careful handling and adherence to safety guidelines due to their potential environmental and health impacts.
The CAS Registry Mumber 5523-03-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 3 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5523-03: (6*5)+(5*5)+(4*2)+(3*3)+(2*0)+(1*3)=75 75 % 10 = 5 So 5523-03-5 is a valid CAS Registry Number.
