7-(2,4-dichloro-phenoxy)-heptanoic acid, also known as 2,4-dichlorophenoxyheptanoic acid, is a synthetic organic compound characterized by its molecular formula C13H16Cl2O3. 7-(2,4-dichloro-phenoxy)-heptanoic acid features a heptanoic acid chain with a 2,4-dichlorophenoxy group attached to the seventh carbon. It is a white crystalline solid with a melting point of approximately 40-42°C. The chemical is known for its herbicidal properties, particularly as a selective post-emergence herbicide used in agriculture to control broadleaf and grassy weeds. It works by inhibiting the enzyme enolpyruvylshikimate-3-phosphate synthase (EPSPS), which is crucial in the biosynthesis of aromatic amino acids in plants, thus disrupting their growth. Due to its chemical structure and mode of action, it is classified as a phenoxy herbicide.
The CAS Registry Mumber 3282-02-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,8 and 2 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3282-02: (6*3)+(5*2)+(4*8)+(3*2)+(2*0)+(1*2)=68 68 % 10 = 8 So 3282-02-8 is a valid CAS Registry Number.
