Chemical Structure
Description
The occurrence of 1,2,4,5,7,8-Hexachloronaphthalene is closely related to chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,2,4,5,7,8-Hexachloronaphthalene (CAS 103426-92-2), a certified reference material (molecular formula C10H2Cl6, MW 334.84 g/mol) for analytical method development and quality control.
Structurally, 1,2,4,5,7,8-Hexachloronaphthalene (C10H2Cl6) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 334.84 g/mol, it falls into the moderately-high-molecular-weight range. 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.
