Chemical Structure
Description
As a certified reference material (CRM), Fmoc-Tyr(PO3(MDPSE)2)-OH 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.
Fmoc-Tyr(PO3(MDPSE)2)-OH (CAS 158817-11-9), molecular formula C54H54NO8PSi2 and molecular weight 932.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, Fmoc-Tyr(PO3(MDPSE)2)-OH is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 932.15 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).
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.
