Chemical Structure
Description
Owing to a nitrile group, an aromatic ring system, 2,3-dimethylpyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 107.15 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).
2,3-dimethylpyridine (CAS 583-61-9) is a high-purity analytical reference standard with the molecular formula C7H9N and a molecular weight of 107.15 g/mol.
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 2,3-dimethylpyridine 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.
