- Health hazard: 急/慢性危害:该化合物在加热分解时释放有毒烟雾。(NTP, 1992)
- Hazard summary: 无致突变性证据;对兔子的皮肤或眼睛无刺激性;[IUCLID] 刺激物;[Alfa Aesar MSDS] 在大鼠腹腔致死剂量研究中引起震颤、发绀和呼吸抑制;[RTECS]
- reactive group: 酰胺和亚胺
- inhalation prophylaxis: 使用局部排风。
- Aspiration risk: 无法给出该物质在空气中达到有害浓度的速率。
- First aid measures: 食入急救: 漱口。喝一两杯水。
- ingestion prevention: 工作期间不要进食、饮水或吸烟。
- exposure prevention: 防止粉尘扩散!
- Spill disposal: 个人防护:根据空气中物质的浓度配备颗粒物过滤呼吸器。将泄漏物质扫入有盖容器中。如适用,先湿润以防止粉尘。用大量水冲洗剩余物。
- Regulatory information: 新西兰 EPA 化学品库存状况:尿素,N,N'-二甲基-:没有单独批准,但可在适当的团体标准下使用
- fire hazard: 可燃。在火灾中释放刺激性或有毒烟雾(或气体)。细分散颗粒在空气中形成爆炸性混合物。
- fire fighting: 使用二氧化碳、水喷雾。
- fire prevention: NO open flames.
- skin prevention: 防护手套。
- interaction: 同时用亚硝酸钠(妊娠第11-15天饮用水中含0.5-0.75%)和N,N'-二甲基脲(妊娠第11天或13天腹腔注射1000毫克/公斤)处理怀孕大鼠和小鼠,产生的致畸效应与用这些甲基脲的亚硝基同系物处理产生的效应相同。
- Eye protection: 佩戴安全护目镜。
- Primary Hazards: 未分类
- reactivity profile: N,N'-二甲基脲是一种酰胺。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易燃气体。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,它们可以作为酸反应。将酰胺与脱水剂(如P2O5或SOCl2)混合会生成相应的腈。这些化合物的燃烧会生成混合氮氧化物(NOx)。
- Symptoms and Signs: 眼部接触:发红。
- Physical Dangers: 如果是粉末或颗粒状,与空气混合可能发生粉尘爆炸。
- Other safety information: 化学品评估:评估-不太可能需要进一步监管以管理环境风险的化学品
- Short-term exposure effects: 该物质对眼睛和皮肤有轻微刺激性
- Air and water reaction: 水溶性。
- Hazard categories and classifications: 特定靶器官毒性 - 重复接触 - 第 2 类(肾脏)
- Non-fire leakage response: 储存注意事项:您应将此材料存放在冰箱中。(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)
