Chemical Structure
Description
The occurrence of Ticlopidine EP Impurity J DiHCl is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ticlopidine EP Impurity J DiHCl (CAS 2056-18-0) is a certified pharmaceutical impurity reference standard with the molecular formula C16H18Cl2N2HCl and a molecular weight of 345.69 g/mol.
Based on its molecular formula C16H18Cl2N2HCl, Ticlopidine EP Impurity J DiHCl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 345.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Ticlopidine EP Impurity J DiHCl 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.
