Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 369.40 g/mol gives 1,1-Bis(4-fluorophenyl)-2-((2-methoxybenzyl)amino)ethan-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,1-Bis(4-fluorophenyl)-2-((2-methoxybenzyl)amino)ethan-1-ol (CAS 338771-02-1), molecular formula C22H21F2NO2 and molecular weight 369.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1,1-Bis(4-fluorophenyl)-2-((2-methoxybenzyl)amino)ethan-1-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.40 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.
