2-Chloro-n-(1,1-dioxo-1lambda6-thiolan-3-yl)-n-ethylpropanamide CAS 879319-18-3 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-n-(1,1-dioxo-1lambda6-thiolan-3-yl)-n-ethylpropanamide.

2-Chloro-n-(1,1-dioxo-1lambda6-thiolan-3-yl)-n-ethylpropanamide (CAS 879319-18-3), molecular formula C9H16ClNO3S and molecular weight 253.75 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-n-(1,1-dioxo-1lambda6-thiolan-3-yl)-n-ethylpropanamide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.75 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.

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.
