Beraprost Impurity 23 CAS 474070-63-8 chemical structure

Description

Beraprost Impurity 23 (CAS 474070-63-8) is a certified pharmaceutical impurity reference standard with the molecular formula C27H34O6 and a molecular weight of 454.56 g/mol.

Beraprost Impurity 23 (C27H34O6) contains a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Beraprost Impurity 23 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.
