The occurrence of (2E,6E,10E)-1-Bromo-3,7,11,15-Tetramethylhexadeca-2,6,10,14-Tetraene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2E,6E,10E)-1-Bromo-3,7,11,15-Tetramethylhexadeca-2,6,10,14-Tetraene (CAS 50848-64-1), molecular formula C20H33Br and molecular weight 353.38 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, an aromatic ring system, (2E,6E,10E)-1-Bromo-3,7,11,15-Tetramethylhexadeca-2,6,10,14-Tetraene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (2E,6E,10E)-1-Bromo-3,7,11,15-Tetramethylhexadeca-2,6,10,14-Tetraene 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.
