As a certified reference material (CRM), 7-Chlorobenzo[b][1,10]phenanthroline 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.
7-Chlorobenzo[b][1,10]phenanthroline (CAS 88149-77-3) is a high-purity analytical reference standard with the molecular formula C16H9ClN2 and a molecular weight of 264.71 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 7-Chlorobenzo[b][1,10]phenanthroline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 264.71 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.
