4-Chloro-3-[(2,6-dimethylmorpholin-4-yl)sulfonyl]benzoic acid CAS 731826-53-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-3-[(2,6-dimethylmorpholin-4-yl)sulfonyl]benzoic acid.

4-Chloro-3-[(2,6-dimethylmorpholin-4-yl)sulfonyl]benzoic acid (CAS 731826-53-2), molecular formula C13H16ClNO5S and molecular weight 333.79 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Chloro-3-[(2,6-dimethylmorpholin-4-yl)sulfonyl]benzoic acid (C13H16ClNO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 333.79 g/mol, it falls into the moderately-high-molecular-weight range. 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.
