Chemical Structure
Description
The occurrence of Ethyl 4-(benzyloxy)-3-chloro-5-ethoxybenzoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 4-(benzyloxy)-3-chloro-5-ethoxybenzoate (CAS 1706463-34-4), a certified reference material (molecular formula C18H19ClO4, MW 334.79 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-(benzyloxy)-3-chloro-5-ethoxybenzoate (C18H19ClO4) 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. 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 Ethyl 4-(benzyloxy)-3-chloro-5-ethoxybenzoate 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.
