Chemical Structure
Description
Structurally, Dequalinium Impurity 6 HI (C20H29IN2HI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 552.27 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.
Dequalinium Impurity 6 HI (CAS CATO-C4X-19366) is a certified pharmaceutical impurity reference standard with the molecular formula C20H29IN2HI and a molecular weight of 552.27 g/mol.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Dequalinium Impurity 6 HI 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.
