Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fmoc-Cys(3-(Boc-amino)-propyl)-OH.
Fmoc-Cys(3-(Boc-amino)-propyl)-OH (CAS 173963-91-2) is a high-purity analytical reference standard with the molecular formula C26H32N2O6S and a molecular weight of 500.62 g/mol.
Based on its molecular formula C26H32N2O6S, Fmoc-Cys(3-(Boc-amino)-propyl)-OH contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 500.62 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.
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.
