CAS 120068-37-3 Fipronil

CAS 120068-37-3 · EC 424-610-5 · Index No 608-055-00-8

Where CAS 120068-37-3 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.
