1-(1H-pyrazole-3-sulfonyl)piperazine hydrobromide (CAS 1795338-17-8), molecular formula C7H12N4O2SHBr and molecular weight 297.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(1H-pyrazole-3-sulfonyl)piperazine hydrobromide (C7H12N4O2SHBr) is characterized by an amide group, a sulfone group, a carboxylic acid 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.
