EC 233-139-2 Boric acid
CAS 10043-35-3 · CAS 11113-50-1 · EC 233-139-2 · EC 234-343-4 · Index No 005-007-00-2
Where EC 233-139-2 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.
