3-Chloro-4-((2,4-dichlorobenzyl)oxy)-5-methoxybenzaldehyde CAS 428479-38-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-4-((2,4-dichlorobenzyl)oxy)-5-methoxybenzaldehyde.

3-Chloro-4-((2,4-dichlorobenzyl)oxy)-5-methoxybenzaldehyde (CAS 428479-38-3) is a high-purity analytical reference standard with the molecular formula C15H11Cl3O3 and a molecular weight of 345.61 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 3-Chloro-4-((2,4-dichlorobenzyl)oxy)-5-methoxybenzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
