Description

Compared with other compounds in its class, the molecular weight of 280.45 g/mol gives 9,12-Octadecadienoic acid (9Z,12Z)-, dimer, homopolymer distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 9,12-Octadecadienoic acid (9Z,12Z)-, dimer, homopolymer (CAS 67922-65-0), a certified reference material (molecular formula C18H32O2, MW 280.45 g/mol) for analytical method development and quality control.

Structurally, 9,12-Octadecadienoic acid (9Z,12Z)-, dimer, homopolymer (C18H32O2) contains 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 280.45 g/mol, it falls into the medium-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).

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.
