2-((S)-5-Amino-5-oxo-2-((S)-pyrrolidine-2-carboxamido)pentanamido)acetic acid CAS 17662-47-4

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-((S)-5-Amino-5-oxo-2-((S)-pyrrolidine-2-carboxamido)pentanamido)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.31 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).

2-((S)-5-Amino-5-oxo-2-((S)-pyrrolidine-2-carboxamido)pentanamido)acetic acid (CAS 17662-47-4), molecular formula C12H20N4O5 and molecular weight 300.31 g/mol, is a CATO reference standard with documented purity and traceability.

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.
