EC 220-239-6 2-methylisothiazol-3(2H)-one
CAS 2682-20-4 · CAS 26172-55-4 · CAS 55965-84-9 · EC 220-239-6 · EC 247-500-7 · Index No 613-326-00-9
Where EC 220-239-6 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.
