Description
As a certified reference material (CRM), 7-Bromo-2,6-dimethylhept-2-ene 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.
7-Bromo-2,6-dimethylhept-2-ene (CAS 87416-83-9) is a high-purity analytical reference standard with the molecular formula C9H17Br and a molecular weight of 205.14 g/mol.
Owing to bromine substitution, 7-Bromo-2,6-dimethylhept-2-ene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.14 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.
