Chemical Structure

Methyl (E)-3,7-dimethylocta-2,6-dienoate CAS 1189-09-9 chemical structure

Description

CATO manufactures Methyl (E)-3,7-dimethylocta-2,6-dienoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Methyl (E)-3,7-dimethylocta-2,6-dienoate (CAS 1189-09-9) is a high-purity analytical reference standard with the molecular formula C11H18O2 and a molecular weight of 182.26 g/mol.

The molecular framework of Methyl (E)-3,7-dimethylocta-2,6-dienoate (C11H18O2) 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).

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.
