EC 244-209-7 Metribuzin
CAS 21087-64-9 · EC 244-209-7 · Index No 606-034-00-8
Where EC 244-209-7 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.
