Chemical Structure
Description
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.
CATO supplies Fosaprepitant-d4 Dimeglumine (CAS CATO-CS298569), a certified reference material (molecular formula C23H18D4F7N4O6PC7H17NO5, MW 813.65 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution, Fosaprepitant-d4 Dimeglumine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 813.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), Fosaprepitant-d4 Dimeglumine 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.
