Chemical Structure

Ethyl (2E,6E)-3,7,11-trimethyldodeca-2,6,10-trienoate CAS 19954-66-6 chemical structure

Description

Ethyl (2E,6E)-3,7,11-trimethyldodeca-2,6,10-trienoate (C17H28O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Ethyl (2E,6E)-3,7,11-trimethyldodeca-2,6,10-trienoate (CAS 19954-66-6), a certified reference material (molecular formula C17H28O2, MW 264.40 g/mol) for analytical method development and quality control.

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.
