Chemical Structure
Description
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.
3-Ethoxy-5-iodo-4-((2-methylbenzyl)oxy)benzoic acid (CAS 1706439-87-3), molecular formula C17H17IO4 and molecular weight 412.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Ethoxy-5-iodo-4-((2-methylbenzyl)oxy)benzoic acid (C17H17IO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 3-Ethoxy-5-iodo-4-((2-methylbenzyl)oxy)benzoic 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.
