Chemical Structure

Ticagrelor EP Impurity B CAS 1788033-05-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 522.57 g/mol gives Ticagrelor EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Ticagrelor EP Impurity B (CAS 1788033-05-5, C23H28F2N6O4S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Ticagrelor EP Impurity B (C23H28F2N6O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 522.57 g/mol, it falls into the moderately-high-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.

As a certified reference material (CRM), Ticagrelor EP Impurity B 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.
