Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4R,4'R)-2,2'-Cyclopentylidenebis[4,5-dihydro-4-(phenylmethyl)oxazole].
CATO supplies (4R,4'R)-2,2'-Cyclopentylidenebis[4,5-dihydro-4-(phenylmethyl)oxazole] (CAS 2005443-99-0), a certified reference material (molecular formula C25H28N2O2, MW 388.50 g/mol) for analytical method development and quality control.
Based on its molecular formula C25H28N2O2, (4R,4'R)-2,2'-Cyclopentylidenebis[4,5-dihydro-4-(phenylmethyl)oxazole] contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 388.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
