Chemical Structure
Description
As a certified reference material (CRM), Ethyl 3-ethoxy-4-((4-fluorobenzyl)oxy)benzoate 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 Ethyl 3-ethoxy-4-((4-fluorobenzyl)oxy)benzoate (CAS 1706445-65-9), a certified reference material (molecular formula C18H19FO4, MW 318.34 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 3-ethoxy-4-((4-fluorobenzyl)oxy)benzoate (C18H19FO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
