Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 3-Ethoxy-4-((3-fluorobenzyl)oxy)benzoic acid (CAS 915918-44-4), a certified reference material (molecular formula C16H15FO4, MW 290.29 g/mol) for analytical method development and quality control.
The molecular framework of 3-Ethoxy-4-((3-fluorobenzyl)oxy)benzoic acid (C16H15FO4) 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.
