Chemical Structure
Description
The occurrence of 4-Ethoxy-3,5-dimethoxybenzaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Ethoxy-3,5-dimethoxybenzaldehyde (CAS 39075-25-7), a certified reference material (molecular formula C11H14O4, MW 210.23 g/mol) for analytical method development and quality control.
The molecular framework of 4-Ethoxy-3,5-dimethoxybenzaldehyde (C11H14O4) 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.
As a certified reference material (CRM), 4-Ethoxy-3,5-dimethoxybenzaldehyde 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.
