2-(3,4-Dichlorophenoxy)benzaldehyde CAS 289717-77-7

Description

Compared with other compounds in its class, the molecular weight of 267.11 g/mol gives 2-(3,4-Dichlorophenoxy)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3,4-Dichlorophenoxy)benzaldehyde (CAS 289717-77-7) is a high-purity analytical reference standard with the molecular formula C13H8Cl2O2 and a molecular weight of 267.11 g/mol.

2-(3,4-Dichlorophenoxy)benzaldehyde (C13H8Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
