Chemical Structure

1,2,4-Trimethylanthracene CAS 20153-28-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2,4-Trimethylanthracene.

1,2,4-Trimethylanthracene (CAS 20153-28-0) is a high-purity analytical reference standard with the molecular formula C17H16 and a molecular weight of 220.31 g/mol.

Owing to a polycyclic aromatic system, 1,2,4-Trimethylanthracene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.31 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).

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.
