Chemical Structure

Tadalafil Impurity 47 CAS 563-96-2 chemical structure

Description

The occurrence of Tadalafil Impurity 47 is closely related to a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Tadalafil Impurity 47 (CAS 563-96-2, C2H2O3H2O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Tadalafil Impurity 47 (C2H2O3H2O) contains a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
