Description
Compared with other compounds in its class, the molecular weight of 348.40 g/mol gives 3-((4-(Methylsulfonyl)piperazin-1-yl)sulfonyl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-((4-(Methylsulfonyl)piperazin-1-yl)sulfonyl)benzoic acid (CAS 385379-94-2), a certified reference material (molecular formula C12H16N2O6S2, MW 348.40 g/mol) for analytical method development and quality control.
3-((4-(Methylsulfonyl)piperazin-1-yl)sulfonyl)benzoic acid (C12H16N2O6S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
