Chemical Structure
Description
2-Methyl-1-(thiophen-2-ylsulfonyl)piperazine hydrochloride (CAS 1261231-55-3), molecular formula C9H14N2O2S2HCl and molecular weight 282.80 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methyl-1-(thiophen-2-ylsulfonyl)piperazine hydrochloride (C9H14N2O2S2HCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2-Methyl-1-(thiophen-2-ylsulfonyl)piperazine hydrochloride 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.
