Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 454.28 g/mol gives Pexidartinib Hydrochloride Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pexidartinib Hydrochloride Salt (CAS 2040295-03-0), molecular formula C20H15ClF3N5HCl and molecular weight 454.28 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H15ClF3N5HCl, Pexidartinib Hydrochloride Salt contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 454.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
