Chemical Structure
Description
As a certified reference material (CRM), 1-[2-(4-Methylphenyl)ethyl]piperazine dihydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1-[2-(4-Methylphenyl)ethyl]piperazine dihydrochloride (CAS 59698-41-8) is a high-purity analytical reference standard with the molecular formula C13H20N2 and a molecular weight of 204.31 g/mol.
Structurally, 1-[2-(4-Methylphenyl)ethyl]piperazine dihydrochloride (C13H20N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 204.31 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
