(2,4-dichloro-6-fluoro-phenoxy)-acetic acid, also known as 2,4-dichlorophenoxyacetic acid-6-fluoro (2,4-D-6-F), is a synthetic auxin-type herbicide derived from 2,4-dichlorophenoxyacetic acid (2,4-D). This chemical compound is characterized by the presence of two chlorine atoms at the 2nd and 4th carbon positions, a fluorine atom at the 6th carbon position, and a phenoxy group attached to an acetic acid chain. It is primarily used to control broadleaf weeds and woody plants by mimicking the action of natural plant hormones, leading to uncontrolled growth and eventually plant death. 2,4-D-6-F is known for its selective herbicidal properties, making it a valuable tool in agriculture for managing weed growth without harming certain crops. However, its use is subject to strict regulations due to potential environmental and health concerns, including its persistence in soil and water, as well as its potential impact on non-target organisms.
The CAS Registry Mumber 443-36-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 3 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 443-36: (5*4)+(4*4)+(3*3)+(2*3)+(1*6)=57 57 % 10 = 7 So 443-36-7 is a valid CAS Registry Number.
