Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
2-Piperazin-1-yl-1-(2-thienyl)ethanone dihydrochloride (CAS 1351612-93-5), molecular formula C10H14N2OSHCl and molecular weight 246.75 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H14N2OSHCl, 2-Piperazin-1-yl-1-(2-thienyl)ethanone dihydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 246.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
