Chemical Structure

Tepotinib Impurity 36 CAS 1103507-25-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 508.57 g/mol gives Tepotinib Impurity 36 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tepotinib Impurity 36 (CAS 1103507-25-0) is a certified pharmaceutical impurity reference standard with the molecular formula C29H28N6O3 and a molecular weight of 508.57 g/mol.

Structurally, Tepotinib Impurity 36 (C29H28N6O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 508.57 g/mol, it falls into the moderately-high-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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
