Chemical Structure

n-[(6-chloropyridin-3-yl)sulfonyl]acetamide CAS 56479-79-9 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 n-[(6-chloropyridin-3-yl)sulfonyl]acetamide.

n-[(6-chloropyridin-3-yl)sulfonyl]acetamide (CAS 56479-79-9) is a high-purity analytical reference standard with the molecular formula C7H7ClN2O3S and a molecular weight of 234.66 g/mol.

Structurally, n-[(6-chloropyridin-3-yl)sulfonyl]acetamide (C7H7ClN2O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 234.66 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
