9,10-Dimethylanthracene , its cas register number is 781-43-1. It also can be called NSC 4220 ; CCRIS 2742 ; and Anthracene, 9,10-dimethyl- . It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While, it's inhaled: Remove from exposure and move to fresh air immediately. Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid. Then you have the ingesting of the product: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
In addition, 9,10-Dimethylanthracene (CAS NO.781-43-1) could be stable under normal temperatures and pressures. It is not compatible with strong oxidants. And also prevent it to broken down into hazardous decomposition products: irritating and toxic fumes and gases.
