Chemical Structure

1,3-Dimethylnaphthalene CAS 575-41-7 chemical structure

Description

Based on its molecular formula C12H12, 1,3-Dimethylnaphthalene contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 156.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

1,3-Dimethylnaphthalene (CAS 575-41-7), molecular formula C12H12 and molecular weight 156.22 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), 1,3-Dimethylnaphthalene 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.
