Chemical Structure
Description
The occurrence of 1,7-Bis(4-bromophenyl)heptane is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,7-Bis(4-bromophenyl)heptane (CAS 140389-09-9), a certified reference material (molecular formula C19H22Br2, MW 410.19 g/mol) for analytical method development and quality control.
Owing to bromine substitution, a polycyclic aromatic system, 1,7-Bis(4-bromophenyl)heptane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 410.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
