Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.55 g/mol gives 1,4,6-Trichloroanthracene-9,10-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,4,6-Trichloroanthracene-9,10-dione (CAS 6470-83-3) is a high-purity analytical reference standard with the molecular formula C14H5Cl3O2 and a molecular weight of 311.55 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 1,4,6-Trichloroanthracene-9,10-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.55 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.
