Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 255.15 g/mol gives 1-(4-Bromophenyl)-4-methylpiperazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-Bromophenyl)-4-methylpiperazine (CAS 130307-08-3), molecular formula C11H15BrN2 and molecular weight 255.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 1-(4-Bromophenyl)-4-methylpiperazine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 255.15 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.
CATO manufactures 1-(4-Bromophenyl)-4-methylpiperazine 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.
