Tetrabenazine Impurity 7 CAS 1187-87-7 chemical structure

Description

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.

Tetrabenazine Impurity 7 (CAS 1187-87-7) is a certified pharmaceutical impurity reference standard with the molecular formula C8H14O and a molecular weight of 126.20 g/mol.

Tetrabenazine Impurity 7 (C8H14O) contains a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
