定義
A powerful plant growth
suppressant and cotton defoliant that is readily
absorbed by leaves and roots. 3-Amino-1,2,4-Triazole inhibits many
aspects of growth and differentiation including cell
division in the primary root meristems in some
plants.
調製方法
3-Amino-1,2,4-Triazole（Amitrole） is synthesized by condensing formic acid with
aminoguanidine and can be purified by recrystallization
from methanol.
一般的な説明
Odorless white crystals or white powder. Bitter taste. Melting point 147-159°C. Sublimes undecomposed at reduced pressure. Used as a post-emergence herbicide.
空気と水の反応
Water soluble. Aqueous solutions are neutral. Dust may form an explosive mixture in air.
反応プロフィール
3-Amino-1,2,4-Triazole is a triazole derivative. The triazoles are a group that contain several derivatives that are highly explosive materials. They are sensitive to heat, friction, and impact. Sensitivity varies with the type substitution to the triazole ring. Metal chelated and halogen substitution of the triazol ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives. It forms chelates with some metals. 3-Amino-1,2,4-Triazole is corrosive to iron, copper and aluminum. Forms salts with most acids and alkalis. It is incompatible with strong oxidizers, strong acids, acid chlorides and acid anhydrides .
危険性
Toxic; carcinogen.
健康ハザード
Amitrole (3-Amino-1,2,4-Triazole) has low acute toxicity;
in experimental animal studies subchronic
exposures were associated with changes in the
thyroid and chronic exposures were
carcinogenic.
Intentional ingestion of a mixture that contained
20 mg/kg amitrole did not cause any
signs of intoxication.1 In one reported case
study, inhalation of a large amount of amitrolecontaining
herbicide was associated with acute
toxic reaction of the lungs.2 Lung injury was
thought to be secondary to direct toxic damage
to the alveolar lining cells. The remarkable lack
of any other reports describing pulmonary toxicity
of this herbicide was noted, in addition to
the presence of other chemicals in the herbicide
solution.
火災危険
Literature sources indicate that Triazol-3-amine is non-combustible.
农业用途
Herbicide, Plant growth regulator: A non-food use herbicide for control of grasses,
woody plants and broad-leaf weeds on hard surface and in
areas where crops are not normally grown.

安全性プロファイル
Confirmed carcinogen with experimental carcinogenic, tumorigenic, and neoplastigenic data. Poison by intraperitoneal route. Moderately toxic by ingestion. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx,. An herbicide and plant growth regulator
職業ばく露
A potential danger to those involved
in the manufacture, formulation, and application of this
postemergence herbicide, which is now limited to noncrop
applications as a herbicide and plant growth regulator.
Some triazoles have been used as rubber components.
発がん性
Amitrole is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
環境運命予測
Soil. When radiolabeled amitrole-5-14C was incubated in a Hagerstown silty clay loam,
50 and 70% of the applied amount evolved as 14CO2 after 3 and 20 days, respectively. In
autoclaved soil, however, no 14CO2 was detected. The chemical degradation in soil was
probably via hydroxyl radicals (Kaufman et al., 1968). The average persistence in soils is
2–4 weeks (Hartley and Kidd, 1987)
Plant.Amitrole is transformed in plants to form the conjugate β-(3-amino-1,2,4-triazol-
1-yl)-α-alanine (Humburg et al., 1989) and/or 3-(3-amino-s-triazole-1-yl)-2-aminopropionic acid (Duke et al., 1991). Amitrole is metabolized in Canada thistl
Surface Water. In pond water, adsorption to suspended sediments was an important
process. The initial half-life was reported to be no more than 68 days. After 120 days,
20% of the applied amount remained (Grzenda et al., 1966). The biodegradation
Photolytic. Direct photolysis of amitrole is not expected to occur since the herbicide
shows little or no absorption greater than 295 nm (Gore et al., 1971)
Chemical/Physical. Reacts with acids and bases forming soluble salts (Hartley and
Kidd, 1987). Emits toxic fumes of nitrogen oxides when heated to decomposition (Sax
and Lewis, 1987); however, incineration with polyethylene results in more than 9

不和合性
Dust may be explosive in air. Keep
away from strong oxidizers; strong acids; light and heat
(decomposes). Corrosive to iron, aluminum, and copper.
Sublimes undecomposed at reduced pressure.
廃棄物の処理
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Amitrol is resistant to hydrolysis and the action of oxidizing
agents. Burning the compound with polyethylene is
reported to result in .99% decomposition.
