Ticlopidine EP Impurity C CAS 89-97-4 chemical structure

Description

Ticlopidine EP Impurity C (CAS 89-97-4) is a certified pharmaceutical impurity reference standard with the molecular formula C7H8ClN and a molecular weight of 141.60 g/mol.

Structurally, Ticlopidine EP Impurity C (C7H8ClN) contains a nitrile group, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 141.60 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
