Uses
Different sources of media describe the Uses of 55335-06-3 differently. You can refer to the following data:
1. Selective postemergence herbicide to control many woody and broad-leaved weeds.
2. Triclopyr is a selective post-emergence herbicide.
Definition
ChEBI: A monocarboxylic acid that is (pyridin-2-yloxy)acetic acid substituted by chloro groups at positions 3, 5 and 6. It is an agrochemical used as a herbicide.
Agricultural Uses
Herbicide: Triclopry is a systemic herbicide used on rice, range
land and pasture, rights-of-way, forestry and grasslands,
including home lawns, for control of broadleaf weeds and
woody plants. Triclopry is usually available as a triclopyr
butoxyethyl ester (BEE) or as a triclopry triethylamine
salt (TEA). Registered for use in the U.S. Some products
may be classified as Restricted Use Pesticides (RUP).

Environmental Fate
Soil. In soil, triclopyr degraded to 3,5,6-trichloro-2-pyridinol and 2-methoxy-3,5,6-
trichloropyridine (Norris et al., 1987). The major route of dissipation from soil is likely
due to microbial degradation (Newton et al., 1990).Fifty-four days after triclopyr was applied to soil at a rate of 5.6 kg/ha, the majority
(65%) remained in the top 10 cm of soil (Lee et al., 1986a).Ashton and Monaco (1991) reported triclopyr had an average half-life of 46 days and
is in?uenced by soil type and climatic conditions.Plant. Lewer and Owen (1989) found 3,5,6-trichloro-2-pyridinol as the major metab-
olite in plants. Cultured soybean cells metabolized triclopyr to dimethyl triclopyr-aspartate
and dimethyl triclopyr-glutamate which can be rehydrolyzed to form the parent compound.At an application rate of 3.4 kg/ha, the dissipation half-life was 3.7 days. At an
application rate of 3.3 kg/ka, the dissipation half-lives of triclopyr in brown, browse and
litter samples were 73.5, 202.3 and 31 days, respectively (Norris et al., 1987).
Metabolic pathway
After 7 days in a soybean cell suspension culture, the
major metabolites of trichlopyr are formed and
identified as the aspartate (major) and glutamate
(minor) amide conjugates.
Metabolism
The average half-life of triclopyr
in soil is 46 days. Because triclopyr is sensitive to light,
the length of time that it remains on the surface may
moderate its persistence. Adsorption to soil is limited and
is governed by the anion exchange capacity. Insignificant
amounts are lost via volatilization. The propensity of
triclopyr to translocate in the environment with soil water,
is unknown.
Toxicity evaluation
The acute oral LD50 of triclopyr
is 692 mg/kg and 577 mg/kg for male and female rat,
respectively. It does not appear to undergo significant
transformation and is excreted in the urine primarily
unchanged.
Check Digit Verification of cas no
The CAS Registry Mumber 55335-06-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,3 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55335-06:
(7*5)+(6*5)+(5*3)+(4*3)+(3*5)+(2*0)+(1*6)=113
113 % 10 = 3
So 55335-06-3 is a valid CAS Registry Number.

Monitoring of the organophosphate pesticide chlorpyrifos in vegetable samples from local markets in Northern Thailand by developed immunoassay

, p. 1 - 14 (2020)
Chlorpyrifos is an organophosphate pesticide that is wildly used among farmers for crop protection. However, there are concerns regarding its contamination in the environment and food chain. In the present study, an in-house indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) specific for detecting chlorpyrifos is developed and validated against gas chromatography–flame photometric detection (GC-FPD) as the conventional method. The developed ic-ELISA was used for detecting chlorpyrifos residue in vegetable samples. The developed ic-ELISA showed good sensitivity to chlorpyrifos at an IC50 of 0.80 μg/kg, with low cross-reactivity to other organophosphate pesticides. The 160 samples were collected from local markets located in the Chiang Rai, Chiang Mai, and Nan provinces in northern Thailand. The positive rate of chlorpyrifos residues in the vegetable samples was 33.8percent, with the highest levels found in cucumbers, coriander, and morning glory, at 275, 145, and 35.3 μg/kg, respectively. The highest median levels of chlorpyrifos found in the detected samples were Chinese cabbage (332 μg/kg), cucumber (146.3 μg/kg) and Chinese Kale (26.95 μg/kg). The developed ic-ELISA is suitable for the rapid quantitation of chlorpyrifos residues.
