Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 579.55 g/mol gives Thalidomide-O-acetamido-PEG4-C2-acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Thalidomide-O-acetamido-PEG4-C2-acid (CAS 2353563-50-3) is a high-purity analytical reference standard with the molecular formula C26H33N3O12 and a molecular weight of 579.55 g/mol.
Thalidomide-O-acetamido-PEG4-C2-acid (C26H33N3O12) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
