Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Oxazole, 2,2′-[1,1′-biphenyl]-2,2′-diylbis[4-(ethoxymethyl)-4,5-dihydro-, (4R,4′R)- (CAS 890933-66-1), a certified reference material (molecular formula C24H28N2O4, MW 408.49 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Oxazole, 2,2′-[1,1′-biphenyl]-2,2′-diylbis[4-(ethoxymethyl)-4,5-dihydro-, (4R,4′R)- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
