57213-69-1 Usage
Uses
Used in Agricultural Applications:
[(3,5,6-Trichloro-2-pyridyl)oxy]acetic acid, compound with triethylamine (1:1) is used as a herbicide for controlling woody plants and broadleaf weeds in various agricultural settings. It is particularly effective in rights-of-way, industrial areas, forestry, railways, rangeland, home lawns, permanent grass pastures, rice, turf, and plantation crops such as palm oil.
Used in Herbicide Formulations:
Triclopyr triethylamine salt is formulated as a selective systemic herbicide that is rapidly absorbed by the green bark, leaves, and roots of plants and distributed throughout the plant. It accumulates in the meristematic tissue (growth region) of the plant, effectively controlling the targeted weeds and plants. Triclopyr is available in various formulations, including soluble and emulsifiable concentrates, powders, pellets, granules, and liquids, making it suitable for a wide range of applications and environments.
Used in the European Union and the United States:
Triclopyr triethylamine salt is registered for use in both the European Union and the United States, making it a widely accepted and effective herbicide for controlling unwanted vegetation in various agricultural and non-agricultural settings.

Environmental Fate
Triclopyr TEA is a grayish white granular solid. It is miscible
in water, slightly soluble in toluene and ethyl acetate, and
practically insoluble in hexane. The Henry’s law constant is
1.15 × 10-14 atm-m3 mol-1; octanol/water partition coefficient
is <5 (1.23).
Air
Volatilization of triclopyr TEA occurs slightly due to its lower
vapor pressure. Low Henry’s law constant indicates little escaping tendency from an aqueous solution. Triclopyr is not
found in air with the exception of spray drift and dust from
pesticide application.
Water
Triclopyr TEA is degraded by photodegradation in water. It is
highly water soluble and dissociates to the weak acid triclopyr
acid and triethanolamine. Triethanolamine rapidly degrades to
CO2 by aerobic microbial processes (half-life 14–18 days).
However, triethanolamine does not degrade under anaerobic
aquatic conditions (half-life >2 years). Triclopyr acid further
dissociates to triclopyr anion, which is the predominant moiety
in the environment. The photolysis of triclopyr acid in aqueous
media is rapid and the half-life is approximately 1 day in water.
The major photolyzed products of triclopyr acid observed were
5-chloro-3,6-dihydroxy-2-pyridinoloxyacetic acid and oxamic
acid in water.
Soil
The major route of dissipation in soil is through microbial
degradation. Moisture favors the microbial growth, which in
turn increases microbial activity. The triclopyr acid is degraded
primarily by microbes with half-lives of 8–18 days to intermediate
compounds 3,5,6-trichloro-2-pyridinol (TCP) and
3,5,6-trichloro-2-methoxypyridine (TMP), and CO2. Triclopyr,
TMP, and TCP have lower soil mobility due to which there
might be limited leaching.
There is no evidence on bioaccumulation of triclopyr in fish
or aquatic nontarget microorganisms.
Toxicity evaluation
The mechanism of action of triclopyr in mammals is still
unclear, although its mechanism of toxicity in plants is well documented. The triclopyr exerts its toxicity in plants by
mimicking the effect of plant growth hormones, which is
similar to its pyridine analog 2,4,5-trichlorophenoxy acetic
acid. Histopathology and clinical chemistry laboratory data
suggest that the liver and kidneys are the primary target organs.
Like any chemical, triclopyr can cause lethality at very high
doses. Triclopyr is excreted primarily through kidneys by a welldefined
active transport process. This process may become
impeded and saturated at very high doses.
Check Digit Verification of cas no
The CAS Registry Mumber 57213-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,1 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57213-69:
(7*5)+(6*7)+(5*2)+(4*1)+(3*3)+(2*6)+(1*9)=121
121 % 10 = 1
So 57213-69-1 is a valid CAS Registry Number.
