Compared with other compounds in its class, the molecular weight of 450.69 g/mol gives 1-Undecanol,11,11'-[1,2-phenylenebis(oxy)]bis- (9CI) 123934-38-3 ACMC-20dsca distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Undecanol,11,11'-[1,2-phenylenebis(oxy)]bis- (9CI) 123934-38-3 ACMC-20dsca (CAS 123934-38-3), molecular formula C28H50O4 and molecular weight 450.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 1-Undecanol,11,11'-[1,2-phenylenebis(oxy)]bis- (9CI) 123934-38-3 ACMC-20dsca is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
