As a certified reference material (CRM), 4-(Butan-2-yl)phenyl (2E)-3-(6-bromo-2H-1,3-benzodioxol-5-yl)prop-2-enoate 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.
4-(Butan-2-yl)phenyl (2E)-3-(6-bromo-2H-1,3-benzodioxol-5-yl)prop-2-enoate (CAS 866136-72-3) is a high-purity analytical reference standard with the molecular formula C20H19BrO4 and a molecular weight of 403.27 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution, 4-(Butan-2-yl)phenyl (2E)-3-(6-bromo-2H-1,3-benzodioxol-5-yl)prop-2-enoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 403.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
