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)-4,4′,5,5′-Tetrahydro-4,4′-bis(1-propylbutyl)-2,2′-bioxazole.
(4R,4′R)-4,4′,5,5′-Tetrahydro-4,4′-bis(1-propylbutyl)-2,2′-bioxazole (CAS 2094987-84-3), molecular formula C20H36N2O2 and molecular weight 336.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4R,4′R)-4,4′,5,5′-Tetrahydro-4,4′-bis(1-propylbutyl)-2,2′-bioxazole (C20H36N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 336.51 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), (4R,4′R)-4,4′,5,5′-Tetrahydro-4,4′-bis(1-propylbutyl)-2,2′-bioxazole 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.
