Ethyl 2,6-pyridinedicarbamate, also known as EPDC, is a chemical compound with the molecular formula C9H10N4O4. It is a white crystalline solid that is primarily used as a herbicide, specifically for controlling grassy weeds in various crops such as soybeans, peanuts, and cotton. EPDC works by inhibiting the enzyme acetohydroxyacid synthase, which is essential for the synthesis of branched-chain amino acids in plants. This inhibition disrupts the plant's growth and ultimately leads to its death. The compound is selective, meaning it affects weeds without harming the desired crop, making it a valuable tool in modern agriculture. It is also known for its relatively low toxicity to mammals and its ability to break down in the environment, which reduces the risk of persistence and potential harm to non-target organisms.
The CAS Registry Mumber 4936-27-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 6 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4936-27: (6*4)+(5*9)+(4*3)+(3*6)+(2*2)+(1*7)=110 110 % 10 = 0 So 4936-27-0 is a valid CAS Registry Number.
