Chemical Structure
Description
The molecular framework of 1-(2-Methylbenzenesulfonyl)piperazine hydrochloride (C11H16N2O2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-(2-Methylbenzenesulfonyl)piperazine hydrochloride (CAS 2037206-52-1), molecular formula C11H16N2O2SHCl and molecular weight 276.78 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
