Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((2-Bromophenyl)sulfonyl)piperazin-2-one.
4-((2-Bromophenyl)sulfonyl)piperazin-2-one (CAS 903302-08-9) is a high-purity analytical reference standard with the molecular formula C10H11BrN2O3S and a molecular weight of 319.17 g/mol.
The molecular framework of 4-((2-Bromophenyl)sulfonyl)piperazin-2-one (C10H11BrN2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-((2-Bromophenyl)sulfonyl)piperazin-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
