Chemical Structure

(9Z,11E)-Methyl Ester 9,11-Octadecadienoate CAS 13058-52-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (9Z,11E)-Methyl Ester 9,11-Octadecadienoate.

(9Z,11E)-Methyl Ester 9,11-Octadecadienoate (CAS 13058-52-1) is a high-purity analytical reference standard with the molecular formula C19H34O2 and a molecular weight of 294.47 g/mol.

Structurally, (9Z,11E)-Methyl Ester 9,11-Octadecadienoate (C19H34O2) 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 294.47 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), (9Z,11E)-Methyl Ester 9,11-Octadecadienoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
