2,4,5-Trimethylnaphthalene CAS 17057-91-9

Description

Compared with other compounds in its class, the molecular weight of 170.25 g/mol gives 2,4,5-Trimethylnaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,4,5-Trimethylnaphthalene (CAS 17057-91-9), molecular formula C13H14 and molecular weight 170.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an aromatic ring system, 2,4,5-Trimethylnaphthalene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 170.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2,4,5-Trimethylnaphthalene 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.
