Chemical Structure
Description
Fmoc-D-Cys(4-methoxytrityl)-OH (CAS 1198791-73-9) is a high-purity analytical reference standard with the molecular formula C38H33NO5S and a molecular weight of 615.74 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Fmoc-D-Cys(4-methoxytrityl)-OH is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes ā including a molecular weight of 615.74 g/mol ā 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.
As a certified reference material (CRM), Fmoc-D-Cys(4-methoxytrityl)-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.
