Chemical Structure

Tetraethyl ((6E,11E)-2,6,12,16-tetramethylheptadeca-2,6,11,15-tetraene-9,9-diyl)bis(phosphonate) CAS 878143-01-2 chemical structure

Description

The occurrence of Tetraethyl ((6E,11E)-2,6,12,16-tetramethylheptadeca-2,6,11,15-tetraene-9,9-diyl)bis(phosphonate) is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tetraethyl ((6E,11E)-2,6,12,16-tetramethylheptadeca-2,6,11,15-tetraene-9,9-diyl)bis(phosphonate) (CAS 878143-01-2), molecular formula C29H54O6P2 and molecular weight 560.68 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Tetraethyl ((6E,11E)-2,6,12,16-tetramethylheptadeca-2,6,11,15-tetraene-9,9-diyl)bis(phosphonate) (C29H54O6P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 560.68 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
