Chemical Structure

(2E,6E,10E)-3,7,11,15-Tetramethyl-2,6,10,14-hexadecatetraenal CAS 13920-12-2 chemical structure

Description

(2E,6E,10E)-3,7,11,15-Tetramethyl-2,6,10,14-hexadecatetraenal (CAS 13920-12-2), molecular formula C20H32O and molecular weight 288.47 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, (2E,6E,10E)-3,7,11,15-Tetramethyl-2,6,10,14-hexadecatetraenal is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.47 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
