Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Oxazole, 2,2′-(ditellurodi-2,1-phenylene)bis[4-ethyl-4,5-dihydro-, (4R,4′R)- (CAS 406909-79-3) is a high-purity analytical reference standard with the molecular formula C22H24N2O2Te2 and a molecular weight of 603.64 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Oxazole, 2,2′-(ditellurodi-2,1-phenylene)bis[4-ethyl-4,5-dihydro-, (4R,4′R)- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 603.64 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.
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.
