2-Methyl-5-phenylpyridine CAS 3256-88-0

Description

The occurrence of 2-Methyl-5-phenylpyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Methyl-5-phenylpyridine (CAS 3256-88-0), molecular formula C12H11N and molecular weight 169.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-Methyl-5-phenylpyridine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 169.22 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).

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-Methyl-5-phenylpyridine 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.
