Chemical Structure
Description
CATO supplies (1S,4s)-1,4-bis(4-bromophenyl)-1,4-bis(methoxymethoxy)cyclohexane (CAS 2177264-24-1), a certified reference material (molecular formula C22H26Br2O4, MW 514.25 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution, (1S,4s)-1,4-bis(4-bromophenyl)-1,4-bis(methoxymethoxy)cyclohexane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 514.25 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.
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.
