Chemical Structure

Tositumomab CAS 192391-48-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 130.91 g/mol gives Tositumomab distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tositumomab (CAS 192391-48-3) is a high-purity analytical reference standard with the molecular formula A[131I] and a molecular weight of 130.91 g/mol.

The molecular framework of Tositumomab (A[131I]) is characterized by iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Tositumomab 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.
