Compared with other compounds in its class, the molecular weight of 154.21 g/mol gives (E,E)-4,6-Dimethyl-2,4-heptadienoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E,E)-4,6-Dimethyl-2,4-heptadienoic Acid (CAS 67513-47-7), molecular formula C9H14O2 and molecular weight 154.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (E,E)-4,6-Dimethyl-2,4-heptadienoic Acid (C9H14O2) 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 154.21 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.
