Chemical Structure
Description
Structurally, Chlorprothixene EP Impurity C HCI (C17H16ClNSHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 338.29 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Chlorprothixene EP Impurity C HCI (CAS 51382-91-3 (free base)) is a certified pharmaceutical impurity reference standard with the molecular formula C17H16ClNSHCl and a molecular weight of 338.29 g/mol.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Chlorprothixene EP Impurity C HCI 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.
