Chemical Structure
Description
The occurrence of 1,1,2,2-Tetrakis(4-methoxyphenyl)ethane-1,2-diol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,1,2,2-Tetrakis(4-methoxyphenyl)ethane-1,2-diol (CAS 19920-00-4) is a high-purity analytical reference standard with the molecular formula C30H30O6 and a molecular weight of 486.56 g/mol.
Based on its molecular formula C30H30O6, 1,1,2,2-Tetrakis(4-methoxyphenyl)ethane-1,2-diol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 486.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
