• 化学的特性

  Orange Paste

• 使用

  A precursor of Diazoethane

• 定義

  ChEBI: A member of the class of N-nitrosoureas that is urea in which one of the nitrogens is substituted by ethyl and nitroso groups.

• 一般的な説明

  Yellow-pink crystals or off-white powder. Sensitive to light.

• 空気と水の反応

  Water soluble. Sensitive to moisture--stability in aqueous solutions depends on pH.

• 反応プロフィール

  N-NITROSO-N-ETHYLUREA is highly reactive. Sensitive to moisture and light. Its stability in aqueous solutions is pH-dependent. Incompatible with water and nucleophilic reagents. Alkaline hydrolysis produces a highly explosive gas. .

• 危険性

  Tumorigen, carcinogen, neoplastigen; teratogen; poison; toxic.

• 健康ハザード

  ACUTE/CHRONIC HAZARDS: N-NITROSO-N-ETHYLUREA is extremely unstable at high pH. It will decompose to extremely unstable decomposition products if acidic conditions are not maintained. When heated to decomposition it emits toxic fumes of nitrogen oxides. Decomposition products may be explosive.

• 火災危険

  Flash point data for N-NITROSO-N-ETHYLUREA are not available; however, N-NITROSO-N-ETHYLUREA is probably combustible.

• 安全性プロファイル

  Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic, and teratogenic data. Poison by ingestion, subcutaneous, intraperitoneal, and intravenous routes. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also N-NITROSO COMPOUNDS.

• 職業ばく露

  Used as a chemical intermediate for dyes and pharmaceuticals; a polymerization inhibitor during the manufacture of vinyl monomers such as styrene; a precursor of diazoethane; accelerator for rubber vulcanization.

• 発がん性

  N-Nitroso-N-ethylurea is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

• 輸送方法

  Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

• 不和合性

  N-nitroso-N-ethylurea is highly reactive. Sensitive to moisture and light. Its stability in aqueous solutions is pH-dependent. Incompatible with water and nucleophilic reagents. Alkaline hydrolysis produces a highly explosive gas. This compound is extremely unstable at high pH. It will decompose to extremely unstable decomposition products if acidic conditions are not maintained. Nitrated organics range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction. Reaction with

• 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.
