As a certified reference material (CRM), Acrylic Acid Impurity 5 Sodium Salt 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.
As a process- or degradation-related impurity, Acrylic Acid Impurity 5 Sodium Salt (CAS 142047-97-0, C4H7O4Na) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Acrylic Acid Impurity 5 Sodium Salt (C4H7O4Na) contains a carbohydrate-derived structure. 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.
