Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 3-ethoxy-5-iodo-4-((4-methylbenzyl)oxy)benzoate.
Methyl 3-ethoxy-5-iodo-4-((4-methylbenzyl)oxy)benzoate (CAS 1706448-08-9), molecular formula C18H19IO4 and molecular weight 426.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-ethoxy-5-iodo-4-((4-methylbenzyl)oxy)benzoate (C18H19IO4) 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).
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.
CATO manufactures Methyl 3-ethoxy-5-iodo-4-((4-methylbenzyl)oxy)benzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
