Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 606.55 g/mol gives Pomalidomide-PEG4-C2-NH2 (TFA) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pomalidomide-PEG4-C2-NH2 (TFA) (CAS 2710221-73-9) is a high-purity analytical reference standard with the molecular formula C23H32N4O8C2HF3O2 and a molecular weight of 606.55 g/mol.
Pomalidomide-PEG4-C2-NH2 (TFA) (C23H32N4O8C2HF3O2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
