Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,4,5-T-2-Ethylhexyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 367.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 2,4,5-T-2-Ethylhexyl Ester (CAS 1928-47-8), a certified reference material (molecular formula C16H21Cl3O3, MW 367.70 g/mol) for analytical method development and quality control.
