Di-tert-butyl2,2'-((2,5-dibromo-1,4-phenylene)bis(oxy))diacetate CAS 1054625-64-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 496.19 g/mol gives Di-tert-butyl2,2'-((2,5-dibromo-1,4-phenylene)bis(oxy))diacetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Di-tert-butyl2,2'-((2,5-dibromo-1,4-phenylene)bis(oxy))diacetate (CAS 1054625-64-7) is a high-purity analytical reference standard with the molecular formula C18H24Br2O6 and a molecular weight of 496.19 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, Di-tert-butyl2,2'-((2,5-dibromo-1,4-phenylene)bis(oxy))diacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 496.19 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.
