(2,4-Dichlor-5-methoxy-phenoxy)-essigsaeure-methylester, also known as methyl 2,4-dichlor-5-methoxyphenoxyacetate, is a chemical compound with the molecular formula C10H10Cl2O4. It is a derivative of 2,4-dichlorophenoxyacetic acid (2,4-D), a widely used herbicide. (2,4-Dichlor-5-methoxy-phenoxy)-essigsaeure-methylester is characterized by the presence of two chlorine atoms at the 2nd and 4th positions of the phenoxy ring, a methoxy group at the 5th position, and a methyl ester group attached to the acetic acid moiety. It is used as an active ingredient in various herbicidal formulations to control broadleaf weeds and grasses in agricultural settings. The compound's effectiveness is attributed to its ability to mimic plant hormones, leading to uncontrolled growth and ultimately the death of the targeted weeds. Due to its chemical structure, it is also known to have some environmental and health concerns, necessitating proper handling and application protocols.
The CAS Registry Mumber 2639-76-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 9 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2639-76: (6*2)+(5*6)+(4*3)+(3*9)+(2*7)+(1*6)=101 101 % 10 = 1 So 2639-76-1 is a valid CAS Registry Number.
