Safety
  • Treatment: EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
  • DOT label: 毒物
  • Health hazard: 急/慢性危害:加热分解时,该化学物质会释放出溴离子和NOx的剧毒烟雾。(NTP, 1992)
  • Hazard summary: 在小鼠腹腔致死剂量研究中引起嗜睡、肌肉无力和呼吸困难(LD50 = 1,400 mg/kg);[RTECS] 可能引起刺激;经有害摄入;可能导致不可逆的不良健康影响;[Acros Organics MSDS] 见尿嘧啶。
  • reactive group: 脂肪族不饱和烃
  • Disposal method: SRP:在审查时,土地处理或填埋(卫生填埋)处置实践的标准正在重大修订中。在实施废物残渣(包括废物污泥)的土地处置之前,咨询环境监管机构以获取可接受的处置实践指导。
  • First aid measures: 食入:不要催吐。如果受害者意识清醒且没有抽搐,给予1-2杯水稀释化学物质,并立即呼叫医院或中毒控制中心。如果医生建议,准备将受害者送往医院。如果受害者抽搐或昏迷,不要经口给予任何东西,确保受害者的气道通畅,让受害者侧卧,头部低于身体。不要催吐。立即将受害者送往医院。(NTP, 1992)
  • exposure pathway: 口服(L626);吸入(L626);皮肤(L626)
  • Toxicity summary: 胸苷磷酸化酶,一种嘧啶补救酶,将5-溴尿嘧啶转化为5-溴脱氧尿苷,这是胸苷的一种诱变类似物。最终,5-溴尿嘧啶作用于DNA。它通过碱基替换诱导随机的DNA点突变。经过数个复制周期后,碱基对将从A-T变为G-C,或从G-C变为A-T,这取决于5-溴尿嘧啶是在DNA分子内还是作为进入的碱基,当它发生烯醇化或离子化时。5-溴尿嘧啶通常与腺嘌呤配对。然而,由于溴原子比C-5原子上的甲基更具电负性,5-溴尿嘧啶的烯醇异构体比例高于胸嘧啶。因此,5-溴尿嘧啶的掺入特别可能导致后续轮次中的碱基配对改变...
  • Regulatory information: 新西兰化学品清单状态:2,4(1H,3H)-嘧啶二酮, 5-溴-:没有单独批准,但可在适当的团体标准下使用
  • fire hazard: 该化学品的闪点数据不可用,但可能是可燃的。(NTP, 1992)
  • fire fighting: 涉及此材料的火灾可以用干化学灭火器、二氧化碳或哈龙灭火器控制。(NTP, 1992)
  • interaction: 由切伦科夫辐射和电离辐射在E. coli AB2487 recA中引起的损伤以加性方式对总体致死性有贡献,而不是以协同方式相互作用。溴尿嘧啶取代通过涉及增强放射敏感性和光敏性的机制增强了高能X射线对E. coli AB2487 recA的致死作用。
  • Toxicity Data: LD50: 1700 mg/kg (大鼠, 腹膜内注射); LD50 1400 mg/kg (小鼠, 腹膜内注射) (T14)
  • Health Effects: 5-溴尿嘧啶是诱变剂(引起突变)和致癌物。吸入可引起呼吸道刺激,皮肤接触可引起皮肤刺激,眼睛接触可引起眼睛刺激。
  • reactivity profile: 一种卤代酰胺。有机酰胺/酰亚胺与偶氮和重氮化合物反应生成有毒气体。有机酰胺/酰亚胺与强还原剂反应生成可燃气体。酰胺是非常弱的碱(比水弱)。酰亚胺的碱性更弱,实际上与强碱反应生成盐。也就是说,它们可以起酸的作用。将酰胺与脱水剂如P2O5或SOCl2混合会生成相应的腈。这些化合物的燃烧产生氮的混合氧化物(NOx)。
  • Symptoms and Signs: 如果大量反复摄入5-溴尿嘧啶,可引起活动过度、腹泻、体重减轻,甚至可能死亡。
  • Isolation and evacuation: 火灾:如果涉及罐、铁路罐车或公路罐车,应在所有方向上隔离800米(1/2英里);同时,考虑在所有方向上初始疏散800米(1/2英里)。(ERG, 2024)
  • Air and water reaction: 不溶于水。
  • non-human toxicity value: LD50 大鼠 ip 1700 mg/kg
  • Hazard categories and classifications: 急性毒性 4 (90.7%)
  • Environmental biodegradability: 厌氧条件:溴尿嘧啶在厌含水层淤浆中培养14个月(含50克沉积物和75毫升地下水)时,被还原脱卤化为化学计量的尿嘧啶(1)。
  • Non-fire leakage response: 储存注意事项:您应在室温下储存此材料。(NTP, 1992)
  • Personal protective equipment (PPE): 推荐呼吸器:在称量和稀释纯测试化学品时,佩戴NIOSH批准的半面罩呼吸器,配备有机蒸气/酸性气体 cartridges(专门用于有机蒸气、HCl、酸性气体和SO2)和粉尘/雾过滤器。(NTP,1992)
  • Carcinogen Classification: IARC未列出。可能引起可遗传的基因损伤。
