Chemical Structure

1,2,3,5,7,8-Hexachloronaphthalene CAS 103426-94-4 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

1,2,3,5,7,8-Hexachloronaphthalene (CAS 103426-94-4) is a high-purity analytical reference standard with the molecular formula C10H2Cl6 and a molecular weight of 334.84 g/mol.

Structurally, 1,2,3,5,7,8-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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 1,2,3,5,7,8-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.
