Chemical Structure

Tinidazole Impurity 3 CAS 28795-33-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 215.27 g/mol gives Tinidazole Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Tinidazole Impurity 3 (CAS 28795-33-7, C8H13N3O2S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Tinidazole Impurity 3 (C8H13N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Tinidazole Impurity 3 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.
