EC number
EC 204-380-0 2-Naphthyloxyacetic acid
CAS 120-23-0 · EC 204-380-0
Where EC 204-380-0 appears: every table entry that prints it among its identifiers, in the newest version of each act this record holds, and every recorded change to those entries. Many entries name a group of substances and print no number, so absence here is not absence from the law. Not legal advice.
