I need some help in purchasing cyclopropane fatty acid standards. The standards are cis 9,10
methylenehexadeconoic acid and cis 9,10 methyleneoctodeconoic acid. I've searched Sigma and
Aldrich catalogues to no avail. Supelco does sell the standards, but it is part of a package ( and too
expensive for my coffers). If anyone has any suggestions please E-mail me at XPII at musicb.mcgill.ca. I
really need these standards for my GC experiment.
