Chemical Structure

Fmoc-D-Cys(Mob)-OH CAS 200354-43-4 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.

Fmoc-D-Cys(Mob)-OH (CAS 200354-43-4) is a high-purity analytical reference standard with the molecular formula C26H25NO5S and a molecular weight of 463.55 g/mol.

Fmoc-D-Cys(Mob)-OH (C26H25NO5S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
