Chemical Structure

Hydroxypropyl betadex EP Impurity B (R-Isomer) CAS 4254-14-2 chemical structure

Description

As a process- or degradation-related impurity, Hydroxypropyl betadex EP Impurity B (R-Isomer) (CAS 4254-14-2, C3H8O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C3H8O2, Hydroxypropyl betadex EP Impurity B (R-Isomer) contains 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 76.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

As a certified reference material (CRM), Hydroxypropyl betadex EP Impurity B (R-Isomer) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
