Chemical Structure
Description
As a certified reference material (CRM), 5-(4-Methoxyphenoxy)pentanoic Acid Methyl Ester 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.
5-(4-Methoxyphenoxy)pentanoic Acid Methyl Ester (CAS 1027079-22-6) is a high-purity analytical reference standard with the molecular formula C13H18O4 and a molecular weight of 238.28 g/mol.
The molecular framework of 5-(4-Methoxyphenoxy)pentanoic Acid Methyl Ester (C13H18O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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.
