Chemical Structure
Description
The molecular framework of 4-((4-Chlorobenzyl)oxy)-3-ethoxybenzoic acid (C16H15ClO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-((4-Chlorobenzyl)oxy)-3-ethoxybenzoic acid (CAS 401827-45-0) is a high-purity analytical reference standard with the molecular formula C16H15ClO4 and a molecular weight of 306.74 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-((4-Chlorobenzyl)oxy)-3-ethoxybenzoic 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.
