Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5',5'',5'''-((((((5-(Bromomethyl)-1,3-phenylene)bis(oxy))bis(methylene))bis(benzene-5,3,1-triyl))tetrakis(oxy))tetrakis(methylene))tetrakis(1,3-dimethoxybenzene).

5,5',5'',5'''-((((((5-(Bromomethyl)-1,3-phenylene)bis(oxy))bis(methylene))bis(benzene-5,3,1-triyl))tetrakis(oxy))tetrakis(methylene))tetrakis(1,3-dimethoxybenzene) (CAS 152811-37-5) is a high-purity analytical reference standard with the molecular formula C57H59BrO14 and a molecular weight of 1047.97 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 5,5',5'',5'''-((((((5-(Bromomethyl)-1,3-phenylene)bis(oxy))bis(methylene))bis(benzene-5,3,1-triyl))tetrakis(oxy))tetrakis(methylene))tetrakis(1,3-dimethoxybenzene) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1047.97 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.

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.
