Chemical Structure
Description
As a certified reference material (CRM), 4-(3-Ethoxyphenyl)-4-oxobutanoic 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.
CATO supplies 4-(3-Ethoxyphenyl)-4-oxobutanoic acid (CAS 905592-33-8), a certified reference material (molecular formula C12H14O4, MW 222.24 g/mol) for analytical method development and quality control.
The molecular framework of 4-(3-Ethoxyphenyl)-4-oxobutanoic acid (C12H14O4) 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.
