Hi Rod:

Yes I mean dimethyl dimethylol hydantoin. And I am looking for purity as well as trace amount determination.

Thank you in advance.

DMDM hydantoin raw material can be assayed by redox titration, available from the supplier. For intact DMDM inproducts, Europe uses HPLC with post-column reaction to separate HCHO and intact DMDMH.
