5-Chloro-2-((2-chloro-4-fluorobenzyl)oxy)benzaldehyde CAS 667436-66-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-2-((2-chloro-4-fluorobenzyl)oxy)benzaldehyde.

CATO supplies 5-Chloro-2-((2-chloro-4-fluorobenzyl)oxy)benzaldehyde (CAS 667436-66-0), a certified reference material (molecular formula C14H9Cl2FO2, MW 299.12 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H9Cl2FO2, 5-Chloro-2-((2-chloro-4-fluorobenzyl)oxy)benzaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 299.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
