Description
CATO manufactures 1-(5-Chloro-2-methoxybenzenesulfonyl)piperazine 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.
1-(5-Chloro-2-methoxybenzenesulfonyl)piperazine (CAS 97630-43-8), molecular formula C11H15ClN2O3S and molecular weight 290.77 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H15ClN2O3S, 1-(5-Chloro-2-methoxybenzenesulfonyl)piperazine contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 290.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
