Chemical Structure

1,3-Bis(4-methoxyphenoxy)benzene CAS 13118-91-7 chemical structure

Description

Based on its molecular formula C20H18O4, 1,3-Bis(4-methoxyphenoxy)benzene contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 322.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1,3-Bis(4-methoxyphenoxy)benzene (CAS 13118-91-7), molecular formula C20H18O4 and molecular weight 322.35 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
