Chemical Structure
Description
As a certified reference material (CRM), 8-Bromo-2,2,4-trimethyl-1,2,3,4-tetrahydroquinoline 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.
8-Bromo-2,2,4-trimethyl-1,2,3,4-tetrahydroquinoline (CAS 1893150-95-2) is a high-purity analytical reference standard with the molecular formula C12H16BrN and a molecular weight of 254.17 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 8-Bromo-2,2,4-trimethyl-1,2,3,4-tetrahydroquinoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 254.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
