Chemical Structure

Tenofovir disoproxil Impurity 95 CAS 58989-06-3 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.

Tenofovir disoproxil Impurity 95 (CAS 58989-06-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H13NO2 and a molecular weight of 131.17 g/mol.

Based on its molecular formula C6H13NO2, Tenofovir disoproxil Impurity 95 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 131.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
