Pomalidomide-PEG5-OH CAS 2140807-34-5

Description

Compared with other compounds in its class, the molecular weight of 493.51 g/mol gives Pomalidomide-PEG5-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pomalidomide-PEG5-OH (CAS 2140807-34-5), molecular formula C23H31N3O9 and molecular weight 493.51 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Pomalidomide-PEG5-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 493.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
