Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 205.04 g/mol gives 2-(3,4-Dichlorophenoxy)acetaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(3,4-Dichlorophenoxy)acetaldehyde (CAS 1017340-78-1) is a high-purity analytical reference standard with the molecular formula C8H6Cl2O2 and a molecular weight of 205.04 g/mol.
The molecular framework of 2-(3,4-Dichlorophenoxy)acetaldehyde (C8H6Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
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.
