Chemical Structure
Description
Based on its molecular formula C19H20N4OC7H8O3SH2O, Niraparib Tosylate Monohydrate contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 510.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Niraparib Tosylate Monohydrate (CAS 1613220-15-7) is a high-purity analytical reference standard with the molecular formula C19H20N4OC7H8O3SH2O and a molecular weight of 510.61 g/mol.
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.
