Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-((2,4-Dimethylphenyl)sulfonyl)piperazin-1-yl)-4-oxobutanoic acid.
CATO supplies 4-(4-((2,4-Dimethylphenyl)sulfonyl)piperazin-1-yl)-4-oxobutanoic acid (CAS 568570-06-9), a certified reference material (molecular formula C16H22N2O5S, MW 354.42 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-(4-((2,4-Dimethylphenyl)sulfonyl)piperazin-1-yl)-4-oxobutanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
