Chemical Structure
Description
The occurrence of Tetradecachloro-p-terphenyl is closely related to chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Tetradecachloro-p-terphenyl (CAS 31710-32-4), a certified reference material (molecular formula C18Cl14, MW 712.53 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, a polycyclic aromatic system, Tetradecachloro-p-terphenyl is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 712.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Tetradecachloro-p-terphenyl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
