Specification

L(+)-Asparagine monohydrate , its cas register number is 5794-13-8. It also can be called L-Asparagine hydrate ; L-2-Aminosuccinamic acid hydrate ; and Asparagine monohydrate . 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.
