 2-Methoxy-5-pyridineboronic acid , its cas register number is 163105-89-3. It also can be called 2-Methoxy-5-pyridinylboronic acid ; and (6-Methoxypyridin-3-yl)boronic Acid . 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.
