1,5-Dichloro-9-methylanthracene CAS 27532-80-5 chemical structure

Description

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

1,5-Dichloro-9-methylanthracene (CAS 27532-80-5) is a high-purity analytical reference standard with the molecular formula C15H10Cl2 and a molecular weight of 261.15 g/mol.

1,5-Dichloro-9-methylanthracene (C15H10Cl2) contains chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
