3,4-Dichloro-6-(difluoromethyl)picolinonitrile CAS 1805326-40-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 223.01 g/mol gives 3,4-Dichloro-6-(difluoromethyl)picolinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,4-Dichloro-6-(difluoromethyl)picolinonitrile (CAS 1805326-40-2), a certified reference material (molecular formula C7H2Cl2F2N2, MW 223.01 g/mol) for analytical method development and quality control.

Owing to a nitrile group, fluorine/chlorine substitution, an aromatic ring system, 3,4-Dichloro-6-(difluoromethyl)picolinonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 3,4-Dichloro-6-(difluoromethyl)picolinonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
