Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 512.00 g/mol gives (S)-(9H-Fluoren-9-yl)methyl (3-(4-(benzyloxy)phenyl)-1-chloro-1-oxopropan-2-yl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-(9H-Fluoren-9-yl)methyl (3-(4-(benzyloxy)phenyl)-1-chloro-1-oxopropan-2-yl)carbamate (CAS 103321-60-4) is a high-purity analytical reference standard with the molecular formula C31H26ClNO4 and a molecular weight of 512.00 g/mol.
(S)-(9H-Fluoren-9-yl)methyl (3-(4-(benzyloxy)phenyl)-1-chloro-1-oxopropan-2-yl)carbamate (C31H26ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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).
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.
