Chemical Structure

2-Methyltriphenylene CAS 1705-84-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 242.31 g/mol gives 2-Methyltriphenylene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyltriphenylene (CAS 1705-84-6) is a high-purity analytical reference standard with the molecular formula C19H14 and a molecular weight of 242.31 g/mol.

Owing to a polycyclic aromatic system, 2-Methyltriphenylene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.31 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
