Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 18-Methoxy-18-oxooctadecanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 18-Methoxy-18-oxooctadecanoic acid (CAS 72849-35-5), a certified reference material (molecular formula C19H36O4, MW 328.49 g/mol) for analytical method development and quality control.
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), 18-Methoxy-18-oxooctadecanoic 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.
