Description

The occurrence of (E)-1-(4-Hydroxyphenyl)-1-[4-(trimethylacetoxy)phenyl]-2-phenylbut-1-ene 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.

(E)-1-(4-Hydroxyphenyl)-1-[4-(trimethylacetoxy)phenyl]-2-phenylbut-1-ene (CAS 177748-17-3), molecular formula C27H28O3 and molecular weight 400.51 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C27H28O3, (E)-1-(4-Hydroxyphenyl)-1-[4-(trimethylacetoxy)phenyl]-2-phenylbut-1-ene 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 400.51 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.

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.
