Chemical Structure

(S)-1-acetylpyrrolidine-3-carboxylic acid CAS 1693726-38-3 chemical structure

Description

The occurrence of (S)-1-acetylpyrrolidine-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-1-acetylpyrrolidine-3-carboxylic acid (CAS 1693726-38-3), molecular formula C7H11NO3 and molecular weight 157.17 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H11NO3, (S)-1-acetylpyrrolidine-3-carboxylic acid 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 157.17 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.
