Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 196.46 g/mol gives 2,4,6-Trichloro-3-methylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4,6-Trichloro-3-methylpyridine (CAS 89487-72-9) is a high-purity analytical reference standard with the molecular formula C6H4Cl3N and a molecular weight of 196.46 g/mol.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 2,4,6-Trichloro-3-methylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 2,4,6-Trichloro-3-methylpyridine 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.
