Chemical Structure

7-Methyl-2-naphthonitrile CAS 38879-96-8 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 7-Methyl-2-naphthonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 167.21 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).

7-Methyl-2-naphthonitrile (CAS 38879-96-8), molecular formula C12H9N and molecular weight 167.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 7-Methyl-2-naphthonitrile 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.
