Chemical Structure

4-Methyl-2-(m-tolyl)pyridine CAS 80635-91-2 chemical structure

Description

As a certified reference material (CRM), 4-Methyl-2-(m-tolyl)pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4-Methyl-2-(m-tolyl)pyridine (CAS 80635-91-2), molecular formula C13H13N and molecular weight 183.25 g/mol, is a CATO reference standard with documented purity and traceability.

4-Methyl-2-(m-tolyl)pyridine (C13H13N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
