Chemical Structure
Description
CATO supplies 5,5'-(Ethane-1,2-diyl)diisophthalic acid (CAS 1774401-34-1), a certified reference material (molecular formula C18H14O8, MW 358.30 g/mol) for analytical method development and quality control.
Structurally, 5,5'-(Ethane-1,2-diyl)diisophthalic acid (C18H14O8) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 358.30 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
