2-(Cyclopentylamino)-1-[(2S)-2-hydroxypyrrolidin-1-yl]ethan-1-one CAS 1881275-77-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Cyclopentylamino)-1-[(2S)-2-hydroxypyrrolidin-1-yl]ethan-1-one.

2-(Cyclopentylamino)-1-[(2S)-2-hydroxypyrrolidin-1-yl]ethan-1-one (CAS 1881275-77-9), molecular formula C11H20N2O2 and molecular weight 212.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H20N2O2, 2-(Cyclopentylamino)-1-[(2S)-2-hydroxypyrrolidin-1-yl]ethan-1-one contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
