546141-56-4 Usage
General Description
4-Amino-6-chloropicolinic acid is a chemical compound with the molecular formula C6H5ClN2O2. 4-Amino-6-chloropicolinic acid is a chlorinated derivative of picolinic acid and contains an amino group and a chloro group attached to a pyridine ring. It is commonly used as a herbicide and is known for its herbicidal activity against a variety of weeds. 4-Amino-6-chloropicolinic acid works by inhibiting the enzyme acetolactate synthase, which is essential for the biosynthesis of branched-chain amino acids in plants. This interference disrupts their growth and eventually leads to their death. It is considered to have a relatively low toxicity to humans and the environment, and it has been used in a variety of agricultural settings to control unwanted vegetation.
Check Digit Verification of cas no
The CAS Registry Mumber 546141-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,6,1,4 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 546141-56:
(8*5)+(7*4)+(6*6)+(5*1)+(4*4)+(3*1)+(2*5)+(1*6)=144
144 % 10 = 4
So 546141-56-4 is a valid CAS Registry Number.

Degradation of benomyl, picloram, and dicamba in a conical apparatus by zero-valent iron powder
Ghauch, Antoine
, p. 1109 - 1117 (2007/10/03)
Reduction of some pesticides (benomyl, picloram, and dicamba) was studied in an aerobic batch conical pilot system to investigate the disappearance of these pesticides on contact with iron powder (20 g/l, 325-mesh). Aqueous buffered solutions of the compounds were added to the system followed by zero-valent iron powder (ZVIP), and the decline in the pesticide concentrations was monitored over time. HPLC analyses show a complete disappearance of picloram (1.20 mg/l) after 20 min of reaction. Benomyl (1.00 mg/l) and dicamba (1.25 mg/l) disappear after 25 and 40 min, respectively. The t50 values ranged from 3 to 5.5 min, and were about slightly less than the t1/2 values reported when the log of the relative HPLC peak area was plotted versus time, where the relative peak area was calculated by dividing the measured peak area by the initial peak area. Pathways for the degradation of the studied pesticides by ZVIP are proposed.
