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-Chloro-1-(3-hydroxypyrrolidin-1-yl)ethan-1-one.
2-Chloro-1-(3-hydroxypyrrolidin-1-yl)ethan-1-one (CAS 1344314-23-3), molecular formula C6H10ClNO2 and molecular weight 163.60 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H10ClNO2, 2-Chloro-1-(3-hydroxypyrrolidin-1-yl)ethan-1-one contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 163.60 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.
