Chemical Structure
Description
The occurrence of (4R,4'R,5S,5'S)-2,2'-Cyclopropylidenebis[4,5-dihydro-4,5-diphenyloxazole] is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4R,4'R,5S,5'S)-2,2'-Cyclopropylidenebis[4,5-dihydro-4,5-diphenyloxazole] (CAS 229184-96-7), molecular formula C33H28N2O2 and molecular weight 484.59 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (4R,4'R,5S,5'S)-2,2'-Cyclopropylidenebis[4,5-dihydro-4,5-diphenyloxazole] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 484.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
