Chemical Structure
Description
1-(3,4-Dimethylphenyl)-2-(piperazin-1-yl)ethan-1-one dihydrochloride (CAS 1281019-20-2), molecular formula C14H20N2OHCl and molecular weight 268.79 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H20N2OHCl, 1-(3,4-Dimethylphenyl)-2-(piperazin-1-yl)ethan-1-one dihydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 1-(3,4-Dimethylphenyl)-2-(piperazin-1-yl)ethan-1-one dihydrochloride 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.
