Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 324.73 g/mol gives 5-(3-Chloro-2-fluorobenzyl)-2,4-dimethoxybenzoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-(3-Chloro-2-fluorobenzyl)-2,4-dimethoxybenzoic Acid (CAS 949465-79-6), a certified reference material (molecular formula C16H14ClFO4, MW 324.73 g/mol) for analytical method development and quality control.
The molecular framework of 5-(3-Chloro-2-fluorobenzyl)-2,4-dimethoxybenzoic Acid (C16H14ClFO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine/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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 5-(3-Chloro-2-fluorobenzyl)-2,4-dimethoxybenzoic 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.
