4-[(2,4-Dichlorobenzyl)oxy]-3-iodobenzaldehyde CAS 443123-69-1

Description

Compared with other compounds in its class, the molecular weight of 407.03 g/mol gives 4-[(2,4-Dichlorobenzyl)oxy]-3-iodobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-[(2,4-Dichlorobenzyl)oxy]-3-iodobenzaldehyde (CAS 443123-69-1), molecular formula C14H9Cl2IO2 and molecular weight 407.03 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H9Cl2IO2, 4-[(2,4-Dichlorobenzyl)oxy]-3-iodobenzaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 407.03 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.
