Chemical Structure

Ziprasidone Impurity 26 CAS 118307-04-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 244.07 g/mol gives Ziprasidone Impurity 26 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ziprasidone Impurity 26 (CAS 118307-04-3) is a certified pharmaceutical impurity reference standard with the molecular formula C10H7Cl2NO2 and a molecular weight of 244.07 g/mol.

Structurally, Ziprasidone Impurity 26 (C10H7Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 244.07 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures Ziprasidone Impurity 26 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
