Description

Compared with other compounds in its class, the molecular weight of 565.57 g/mol gives (S)-1-(1-(((9H-Fluoren-9-yl)methoxy)carbonyl)pyrrolidin-2-yl)-1,4,7,10-tetraoxo-2,5,8,11-tetraazatridecan-13-oic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-1-(1-(((9H-Fluoren-9-yl)methoxy)carbonyl)pyrrolidin-2-yl)-1,4,7,10-tetraoxo-2,5,8,11-tetraazatridecan-13-oic acid (CAS 1450625-21-4), a certified reference material (molecular formula C28H31N5O8, MW 565.57 g/mol) for analytical method development and quality control.

Structurally, (S)-1-(1-(((9H-Fluoren-9-yl)methoxy)carbonyl)pyrrolidin-2-yl)-1,4,7,10-tetraoxo-2,5,8,11-tetraazatridecan-13-oic acid (C28H31N5O8) contains a nitrogen-containing heterocyclic scaffold, 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 565.57 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).

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.
