Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-Ethylhexyl Methyl Phthalate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
