Chemical Structure

BPA Impurity 2 CAS 2828446-99-5 chemical structure

Description

As a process- or degradation-related impurity, BPA Impurity 2 (CAS 2828446-99-5, C20H30BNO6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

BPA Impurity 2 (C20H30BNO6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
