Chemical Structure
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 1,2,3,4,6,7-Hexachloronaphthalene (CAS 103426-96-6), a certified reference material (molecular formula C10H2Cl6, MW 334.84 g/mol) for analytical method development and quality control.
The molecular framework of 1,2,3,4,6,7-Hexachloronaphthalene (C10H2Cl6) is characterized by chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1,2,3,4,6,7-Hexachloronaphthalene 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.
