Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 518.20 g/mol gives Purealidin A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Purealidin A (CAS 134850-51-4), molecular formula C17H22Br2N6O3 and molecular weight 518.20 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H22Br2N6O3, Purealidin A contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 518.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Purealidin A 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.
