cis-9,10-Methylenooctadecanoic acid CAS 4675-61-0

Description

Compared with other compounds in its class, the molecular weight of 296.49 g/mol gives cis-9,10-Methylenooctadecanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies cis-9,10-Methylenooctadecanoic acid (CAS 4675-61-0), a certified reference material (molecular formula C19H36O2, MW 296.49 g/mol) for analytical method development and quality control.

Based on its molecular formula C19H36O2, cis-9,10-Methylenooctadecanoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 296.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), cis-9,10-Methylenooctadecanoic acid 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.
