Chemical Structure

2,6-Dichloro-4-methylpyridine-3,5-dicarbonitrile CAS 18603-33-3 chemical structure

Description

The occurrence of 2,6-Dichloro-4-methylpyridine-3,5-dicarbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,6-Dichloro-4-methylpyridine-3,5-dicarbonitrile (CAS 18603-33-3), a certified reference material (molecular formula C8H3Cl2N3, MW 212.04 g/mol) for analytical method development and quality control.

Structurally, 2,6-Dichloro-4-methylpyridine-3,5-dicarbonitrile (C8H3Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 212.04 g/mol, it falls into the medium-molecular-weight range. 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).

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 2,6-Dichloro-4-methylpyridine-3,5-dicarbonitrile 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.
