4-[4-(4-chlorobenzenesulfonyl)piperazin-1-yl]-4-oxobutanoic acid CAS 560995-22-4

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-[4-(4-chlorobenzenesulfonyl)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 360.81 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.

CATO supplies 4-[4-(4-chlorobenzenesulfonyl)piperazin-1-yl]-4-oxobutanoic acid (CAS 560995-22-4), a certified reference material (molecular formula C14H17ClN2O5S, MW 360.81 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
