Moderately toxic. When heated to decomposition it emits toxic fumes of Cl⁻, SO_x, and NO_x.

The synonyms of Ampicillin-oxacillin mixture (CAS NO.8067-85-4) are (2S,5R,6R)-6-[[(2R)-2-amino-2-phenyl-acetyl]amino]-3,3-dimethyl-7-oxo- 4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid ; (2S,5R,6R)-3,3-di methyl-6-[(5-methyl-3-phenyl-oxazole-4-carbonyl)amino]-7-oxo-4-thia-1- azabicyclo[3.2.0]heptane-2-carboxylic acid ; Broadcillin . Ampicillin-oxacillin mixture (CAS NO.8067-85-4) is moderate toxic. It is flammable. Ampicillin-oxacillin mixture (CAS NO.8067-85-4) will produce toxic nitrogen oxides, sulfur oxides and chloride fumes by heat. So the storage environment should be ventilate, low-temperature and dry.
