Chemical Structure
Description
The occurrence of Ondansetron EP Impurity F is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ondansetron EP Impurity F (CAS 693-98-1) is a certified pharmaceutical impurity reference standard with the molecular formula C4H6N2 and a molecular weight of 82.10 g/mol.
Owing to a nitrile group, Ondansetron EP Impurity F is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 82.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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 Ondansetron EP Impurity F 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.
