Chemical Structure
Description
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.
1-(4-Bromo-2-fluorophenyl)-4-methylpiperazine (CAS 1352207-52-3) is a high-purity analytical reference standard with the molecular formula C11H14BrFN2 and a molecular weight of 273.14 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution, 1-(4-Bromo-2-fluorophenyl)-4-methylpiperazine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 273.14 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.
As a certified reference material (CRM), 1-(4-Bromo-2-fluorophenyl)-4-methylpiperazine 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.
