Chemical Structure
Description
The occurrence of 1,5-Dibromo-9,10-bis(phenylethynyl)anthracene is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5-Dibromo-9,10-bis(phenylethynyl)anthracene (CAS 84870-39-3), molecular formula C30H16Br2 and molecular weight 536.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, a polycyclic aromatic system, 1,5-Dibromo-9,10-bis(phenylethynyl)anthracene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 536.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
