Chemical Structure

Tenofovir disoproxil Impurity 58 CAS 1611-31-0 chemical structure

Description

As a process- or degradation-related impurity, Tenofovir disoproxil Impurity 58 (CAS 1611-31-0, C6H15O4P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C6H15O4P, Tenofovir disoproxil Impurity 58 contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 182.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
