α-Methyl-α-(4-chlorphenoxy)-4-methylhydrozimtsaeure, also known as MCPA, is a widely used herbicide belonging to the phenoxy family. It is an organic compound with the chemical formula C11H13ClO3, characterized by a 4-chlorophenoxy group attached to a methylhydrocinnamic acid structure. MCPA is effective in controlling broadleaf weeds and grasses in various agricultural settings, particularly in cereal crops and pastures. It works by inhibiting the synthesis of auxins, which are essential for plant growth, leading to the death of the targeted weeds. Due to its selective action and relatively low toxicity to mammals, MCPA is a popular choice among farmers. However, it is crucial to follow proper application guidelines to minimize environmental impact and ensure the safety of non-target organisms.
The CAS Registry Mumber 36304-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,3,0 and 4 respectively; the second part has 2 digits, 1 and 3 respectively. Calculate Digit Verification of CAS Registry Number 36304-13: (7*3)+(6*6)+(5*3)+(4*0)+(3*4)+(2*1)+(1*3)=89 89 % 10 = 9 So 36304-13-9 is a valid CAS Registry Number.
