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.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(4-(((tert-butoxycarbonyl)amino)methyl)phenyl)acetic acid (CAS 205049-68-9) is a high-purity analytical reference standard with the molecular formula C29H30N2O6 and a molecular weight of 502.56 g/mol.
Structurally, (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(4-(((tert-butoxycarbonyl)amino)methyl)phenyl)acetic acid (C29H30N2O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 502.56 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
