Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.93 g/mol gives 2-Chloro-6-methoxy-4-(trichloromethyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-6-methoxy-4-(trichloromethyl)pyridine (CAS 7159-34-4) is a high-purity analytical reference standard with the molecular formula C7H5Cl4NO and a molecular weight of 260.93 g/mol.
The molecular framework of 2-Chloro-6-methoxy-4-(trichloromethyl)pyridine (C7H5Cl4NO) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
