Bis(11-bromoundecyl) 4,4'-(((1,2-diphenylethene-1,2-diyl)bis(4,1-phenylene))bis(ethyne-2,1-diyl))(Z)-dibenzoate CAS 1642109-29-2

Description

Bis(11-bromoundecyl) 4,4'-(((1,2-diphenylethene-1,2-diyl)bis(4,1-phenylene))bis(ethyne-2,1-diyl))(Z)-dibenzoate (C66H70Br2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Bis(11-bromoundecyl) 4,4'-(((1,2-diphenylethene-1,2-diyl)bis(4,1-phenylene))bis(ethyne-2,1-diyl))(Z)-dibenzoate (CAS 1642109-29-2) is a high-purity analytical reference standard with the molecular formula C66H70Br2O4 and a molecular weight of 1087.07 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
