Chemical Structure

Cis-8,11,14-Eicosatrienoic Acid Methyl Ester CAS 21061-10-9 chemical structure

Description

Structurally, Cis-8,11,14-Eicosatrienoic Acid Methyl Ester (C21H36O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 320.51 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).

Cis-8,11,14-Eicosatrienoic Acid Methyl Ester (CAS 21061-10-9), molecular formula C21H36O2 and molecular weight 320.51 g/mol, is a CATO reference standard with documented purity and traceability.

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.
