As a certified reference material (CRM), ((2E,4E)-5-(4-methoxy-2,3,6-trimethylphenyl)-3-methylpenta-2,4-dien-1-yl)triphenylphosphonium bromide 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.
CATO supplies ((2E,4E)-5-(4-methoxy-2,3,6-trimethylphenyl)-3-methylpenta-2,4-dien-1-yl)triphenylphosphonium bromide (CAS 54757-44-7), a certified reference material (molecular formula C34H36OPBr, MW 571.54 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, ((2E,4E)-5-(4-methoxy-2,3,6-trimethylphenyl)-3-methylpenta-2,4-dien-1-yl)triphenylphosphonium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 571.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
