Chemical Structure

(2E,4E)-2,4-Dodecadienoic Acid CAS 24738-48-5 chemical structure

Description

(2E,4E)-2,4-Dodecadienoic Acid (CAS 24738-48-5) is a high-purity analytical reference standard with the molecular formula C12H20O2 and a molecular weight of 196.29 g/mol.

The molecular framework of (2E,4E)-2,4-Dodecadienoic Acid (C12H20O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
