Chemical Structure
Description
1-(3-Bromopyridin-2-yl)-4-methylpiperazine (CAS 87394-59-0) is a high-purity analytical reference standard with the molecular formula C10H14BrN3 and a molecular weight of 256.14 g/mol.
1-(3-Bromopyridin-2-yl)-4-methylpiperazine (C10H14BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 1-(3-Bromopyridin-2-yl)-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.
