Chemical Structure
Description
As a certified reference material (CRM), Fosamprenavir 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.
Fosamprenavir (CAS 226700-79-4), molecular formula C25H36N3O9PS and molecular weight 585.61 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C25H36N3O9PS, Fosamprenavir contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 585.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
