CAS 120-82-1 Trichlorobenzene
CAS 120-82-1 · EC 204-428-0 · Index No 602-087-00-6
Where CAS 120-82-1 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.
