Is Ethyl (2Z)-3-amino-2-butenoate (CAS: 626-34-6) safe?

Ethyl (2Z)-3-amino-2-butenoate is considered relatively safe for industrial use. However, it is important to handle it with care due to its flammability. Protective equipment, such as gloves and goggles, should be worn. Storage should be in a cool, well-ventilated area, away from heat and sources of ignition. Toxicology data suggests that it is not highly toxic, but inhalation or contact with skin should be avoided.
