Chemical Structure
Description
The occurrence of (Ethane-1,1,1-triyltris(oxy))tribenzene 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.
(Ethane-1,1,1-triyltris(oxy))tribenzene (CAS 49758-91-0), molecular formula C20H18O3 and molecular weight 306.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (Ethane-1,1,1-triyltris(oxy))tribenzene (C20H18O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 306.36 g/mol, it falls into the moderately-high-molecular-weight range. 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.
