Description

Compared with other compounds in its class, the molecular weight of 456.70 g/mol gives 3,5,7,9,11,13,15,17,19-Eicosanonaen-2-one, 5,9,14,18-tetramethyl-20-(2,6,6-trimethyl-1-cyclohexen-1-yl)-, (3E,5E,7E,9E,11E,13E,15E,17E,19E)- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,5,7,9,11,13,15,17,19-Eicosanonaen-2-one, 5,9,14,18-tetramethyl-20-(2,6,6-trimethyl-1-cyclohexen-1-yl)-, (3E,5E,7E,9E,11E,13E,15E,17E,19E)- (CAS 3604-90-8), a certified reference material (molecular formula C33H44O, MW 456.70 g/mol) for analytical method development and quality control.

Structurally, 3,5,7,9,11,13,15,17,19-Eicosanonaen-2-one, 5,9,14,18-tetramethyl-20-(2,6,6-trimethyl-1-cyclohexen-1-yl)-, (3E,5E,7E,9E,11E,13E,15E,17E,19E)- (C33H44O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 456.70 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
