Chemical Structure

Sunitinib Impurity 44 CAS 110-72-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 88.15 g/mol gives Sunitinib Impurity 44 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sunitinib Impurity 44 (CAS 110-72-5) is a certified pharmaceutical impurity reference standard with the molecular formula C4H12N2 and a molecular weight of 88.15 g/mol.

Owing to an organic framework, Sunitinib Impurity 44 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 88.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Sunitinib Impurity 44 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.
