Chemical Structure

(S)-2-chloro-1-(pyrrolidin-2-yl)ethan-1-one CAS 38491-75-7 chemical structure

Description

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.

(S)-2-chloro-1-(pyrrolidin-2-yl)ethan-1-one (CAS 38491-75-7), molecular formula C6H10ClNO and molecular weight 147.60 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-2-chloro-1-(pyrrolidin-2-yl)ethan-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
