Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,3,11,12-Tetrachloro-9,10-dihydro-9,10-ethanoanthracene (CAS 55089-37-7), a certified reference material (molecular formula C16H10Cl4, MW 344.06 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, a polycyclic aromatic system, 2,3,11,12-Tetrachloro-9,10-dihydro-9,10-ethanoanthracene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.06 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.
As a certified reference material (CRM), 2,3,11,12-Tetrachloro-9,10-dihydro-9,10-ethanoanthracene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
