Chemical Structure
Description
n-(2-Bromophenyl)tetrahydro-2h-pyran-4-amine (CAS 1154890-16-0) is a high-purity analytical reference standard with the molecular formula C11H14BrNO and a molecular weight of 256.14 g/mol.
n-(2-Bromophenyl)tetrahydro-2h-pyran-4-amine (C11H14BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), n-(2-Bromophenyl)tetrahydro-2h-pyran-4-amine 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.
