Chemical Structure

Apixaban Impurity 104 CAS 5819-34-1 chemical structure

Description

Structurally, Apixaban Impurity 104 (C4H5ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 136.53 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a process- or degradation-related impurity, Apixaban Impurity 104 (CAS 5819-34-1, C4H5ClO3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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), Apixaban Impurity 104 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.
