What Is (E,E,E)-2,7-Dimethylocta-2,4,6-trienedial?
(E,E,E)-2,7-Dimethylocta-2,4,6-trienedial (CAS 5056-17-7) is an all-E conjugated triene dialdehyde, also known as 12,12′-di-apo-carotenedial. Molecular formula C10H12O2; molecular weight about 164.2 g/mol. Always match CAS 5056-17-7 on the batch COA.
Literature and supplier catalogs describe it as an apocarotenoid-related electrophilic dialdehyde used as a specialty building block and research reference in carotenoid cleavage / lipid-oxidation pathway studies, and as an intermediate for further polyene synthesis (e.g. Wittig / HWE-type routes). Monuo Chemical supplies this material as a specialty chemical raw material under Custom synthesis, with batch identity documentation (COA / SDS). Finished-product claims, labeling and local regulatory filings remain the brand manufacturer’s responsibility. Confirm grade and assay against the batch COA for your intended method.
