1-(4-Piperazin-1-yl-phenyl)ethanone 1-(4-Acetylphenyl)piperazine 1-(p-Acetylphenyl)piperazine 1-[4-(1-Piperazinyl)phenyl]-1-ethanone 4'-Piperazinoacetophenone N-(4-Acetylphenyl)piperazine 51639-48-6 CAS 51639-48-6 chemical structure

Description

As a certified reference material (CRM), 1-(4-Piperazin-1-yl-phenyl)ethanone 1-(4-Acetylphenyl)piperazine 1-(p-Acetylphenyl)piperazine 1-[4-(1-Piperazinyl)phenyl]-1-ethanone 4'-Piperazinoacetophenone N-(4-Acetylphenyl)piperazine 51639-48-6 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-(4-Piperazin-1-yl-phenyl)ethanone 1-(4-Acetylphenyl)piperazine 1-(p-Acetylphenyl)piperazine 1-[4-(1-Piperazinyl)phenyl]-1-ethanone 4'-Piperazinoacetophenone N-(4-Acetylphenyl)piperazine 51639-48-6 (CAS 51639-48-6) is a high-purity analytical reference standard with the molecular formula C12H22N2O and a molecular weight of 210.32 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 1-(4-Piperazin-1-yl-phenyl)ethanone 1-(4-Acetylphenyl)piperazine 1-(p-Acetylphenyl)piperazine 1-[4-(1-Piperazinyl)phenyl]-1-ethanone 4'-Piperazinoacetophenone N-(4-Acetylphenyl)piperazine 51639-48-6 is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
