Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2,5-Bis(prop-2-yn-1-yloxy)terephthalohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.29 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).
2,5-Bis(prop-2-yn-1-yloxy)terephthalohydrazide (CAS 2564821-81-2), molecular formula C14H14N4O4 and molecular weight 302.29 g/mol, is a CATO reference standard with documented purity and traceability.
