Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (2E,4E,6E,8E,10E)-Diethyl 4,9-dimethyldodeca-2,4,6,8,10-pentaenedioate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.38 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).
(2E,4E,6E,8E,10E)-Diethyl 4,9-dimethyldodeca-2,4,6,8,10-pentaenedioate (CAS 53163-55-6), molecular formula C18H24O4 and molecular weight 304.38 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
