• 反応プロフィール

  3,6-Dihydroxypyridazine can be decomposed by oxidizing agents. 3,6-Dihydroxypyridazine can also be decomposed by strong acids. 3,6-Dihydroxypyridazine forms water-soluble alkali-metal and amine salts. 3,6-Dihydroxypyridazine is slightly acidic and may be titrated as a monobasic acid. Mild oxidation produces a compound which reacts instantly with dienes at -107° F to form crystalline derivatives. 3,6-Dihydroxypyridazine is slightly corrosive to iron and zinc. 3,6-Dihydroxypyridazine is incompatible with pesticides that are highly alkaline in reaction. In the presence of heavy metal and iron, zinc, calcium and magnesium ions, sparingly-soluble salts are formed.

• 危険性

  Toxic by ingestion. Questionable carcinogen.

• 健康ハザード

  Inhalation of dust causes irritation of nose and throat. Contact with eyes or skin causes irritation. Ingestion has been observed to cause tremors and muscle spasms in test animals.

• 火災危険

  Special Hazards of Combustion Products: Toxic nitrogen oxides are produced.

• 作用机制

  オーキシンの生理作用と拮抗

• 农业用途

  Herbicide, Plant growth regulator, Fungicide: Banned for use in EU countries. Actively registered for use in the U.S. Maleic hydrazide is a plant growth regulator (sprout inhibitor) and herbicide that is registered for use on tobacco, potatoes, onions, non-bearing citrus, turf, utility and highway rights-of-way, airports, industrial land, lawns, recreational areas, ornamental/shade trees and ornamental plants. Most of the use of maleic hydrazide in the U.S. is on tobacco.

• 職業ばく露

  Maleic hydrazide is a pyridazine/ pyridazinone herbicide, plant growth regulator, and fungicide that is registered for use on tobacco, potatoes, onions, nonbearing citrus, turf, utility and highway rights-of-way, airports, industrial land, lawns, recreational areas, ornamental/ shade trees and ornamental plants. Most of the use of maleic hydrazide in the United States is on tobacco. Banned for use in EU countries. Actively registered for use in the United States

• 発がん性

  Mice fed up to 3 mg/kg for 320 ‘days showed no carcinogenic effect when sacrificed at 2 years of age. Mice fed 0, 1000, 3200, and 10,000 ppm in the diet in 23 months showed no oncogenic effect. Rats were fed diets providing doses of 0, 25, 500, or 1000 mg/kg. Occasional increases in tumor incidences were seen, but as these were not consistent between the two sexes and did not achieve statistical significance, they are considered not attributable to maleic hydrazide.
  Application of maleic hydrazide to the skin three times a week up to a cumulative dose of 300mg was not carcinogenic . Oral treatment of dogs and rats for 17–28 months resulted in no excess cancer in any tissue or organs. Subcutaneous injections of maleic hydrazide in newborn mice produced a very slight increase in liver tumors, although this finding is generally considered negative. A study in which maleic hydrazide was given subcutaneously to mice (55 mg total over 49 weeks) showed no evidence of a carcinogenic response was seen.

• 環境運命予測

  Soil. The half-life in soil was reported to be 2–8 weeks (Hartley and Kidd, 1987). When maleic hydrazide was applied to muck, sand and clay at concentrations of 0.7 and 2.7, 1.0 and 3.75 and 0.85 and 3.4 ppm, 86 and 100, 87 and 100 and 47 and 67% degradation yields were obtained, respectively (Hoffman et al., 1962).
  Plant. Major plant metabolites include fumaric, succinic and maleic acids (Hartley and Kidd, 1987).
  Photolytic. In water, maleic hydrazide showed an absorption maximum at 300 nm indicating direct photolysis should occur (Gore et al., 1971).
  Chemical/Physical. Reacts with alkalies and amines forming water-soluble salts (Hartley and Kidd, 1987). Decomposed by oxidizing acids releasing nitrogen (Worthing and Hance, 1991). Decomposes at 260°C (Windholz et al., 1983) releasing toxic fumes of nitrogen oxides (Sax and Lewis, 1987).

• 輸送方法

• 純化方法

  Crystallise the hydrazide from water. Dry it at ~100o over P2O5. [Beilstein 24 III/IV 1186.]

• 不和合性

  Dust may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Slightly corrosive to iron and zinc. Maleic hydrazide forms water-soluble alkali-metal and amine salts. It is slightly acidic and may be titrated as a monobasic acid. Mild oxidation produces a compound which reacts instantly with dienes at 277C/ 2 107F to form crystalline derivatives. It is incompatible with pesticides that are highly alkaline in reaction. This chemical is slightly corrosive to iron and zinc. In the presence of heavy metal and iron, zinc, calcium, and magnesium ions, sparingly soluble salts are formed.

• 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 to EPA regulations governing storage, transportation, treatment, and waste disposal. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
