Pentachlorphenoxy-methoxy-methan, also known as 2,3,5,6-tetrachlorophenoxyacetic acid, is a synthetic chemical compound with the molecular formula C8H5Cl4O3. It is a derivative of 2,4,5-T, a component of the herbicide 2,4,5-TP (Silvex), which was widely used for controlling broadleaf weeds and woody plants. The compound is characterized by its chlorinated phenoxy structure, which contributes to its herbicidal properties. However, due to its potential environmental and health risks, including persistence in soil and water, as well as its toxic effects on humans and wildlife, the use of 2,4,5-T and its derivatives has been largely discontinued in many countries. The compound's chemical structure and properties make it a subject of interest in studies on the environmental fate and remediation of persistent organic pollutants.
The CAS Registry Mumber 7382-36-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,8 and 2 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 7382-36: (6*7)+(5*3)+(4*8)+(3*2)+(2*3)+(1*6)=107 107 % 10 = 7 So 7382-36-7 is a valid CAS Registry Number.
