Talk:Marker degradation

Update External Link
I am the program coordinator of the ACS-National Historic Chemical Landmarks program. I have updated the references to ACS-NHCL web content, as those pages have been replaced by (http://portal.acs.org/portal/PublicWebSite/education/whatischemistry/landmarks/progesteronesynthesis/index.htm). The old pages will be discontinued in the coming months. KLindblom (talk) 20:21, 5 June 2012 (UTC)
