What regulatory guidelines apply to CAS 54-35-3 (Hydrogen (2S,5R,6R)-3,3-dimethyl-7-oxo-6-[(phenylacetyl)amino]-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate - 2-(diethylamino)ethyl 4-aminobenzoate (1:1:1))?

CAS 54-35-3 (Hydrogen (2S,5R,6R)-3,3-dimethyl-7-oxo-6-[(phenylacetyl)amino]-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate - 2-(diethylamino)ethyl 4-aminobenzoate (1:1:1)) falls under the scope of the Chemicals of Very High Concern (vCPCs) list under REACH and may require authorization if it meets the criteria.
