Chemical Structure
Description
(4S,4′S)-2,2′-(1,8-Anthracenediyl)bis[4,5-dihydro-4-(phenylmethyl)oxazole] (CAS 873843-23-3) is a high-purity analytical reference standard with the molecular formula C34H28N2O2 and a molecular weight of 496.60 g/mol.
Structurally, (4S,4′S)-2,2′-(1,8-Anthracenediyl)bis[4,5-dihydro-4-(phenylmethyl)oxazole] (C34H28N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 496.60 g/mol, it falls into the moderately-high-molecular-weight range. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (4S,4′S)-2,2′-(1,8-Anthracenediyl)bis[4,5-dihydro-4-(phenylmethyl)oxazole] meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
