5-Chloro-2-methylbenzoxazole Specification
Polymerization of the 5-Chloro-2-methylbenzoxazole(19219-99-9) is sensitive with light, and you must not take it with strong oxidizing agents and strong acids. And also prevent it to broken down into hazardous decomposition products: oxides of nitrogen,carbon dioxide,carbon monoxide,hydrogen chloride.
In addition, 5-Chloro-2-methylbenzoxazole(19219-99-9) is hazardous,so the first aid measures should be known .Such as:
Skin: Get medical aid. Should flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.Then get medical aid soon.
Inhalation: Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen.And as soon as to get medical aid. If not breathing, give artificial respiration.
Ingestion: Wash mouth out with water,and get medical aid immediately.
