Istradefylline Impurity 15 CAS 89073-60-9

Description

Compared with other compounds in its class, the molecular weight of 212.21 g/mol gives Istradefylline Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Istradefylline Impurity 15 (CAS 89073-60-9), a pharmacopoeial impurity reference standard (molecular formula C8H12N4O3, MW 212.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Istradefylline Impurity 15 (C8H12N4O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 212.21 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
