(((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(dicyclohexylphosphine) CAS 82239-68-7

Description

(((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(dicyclohexylphosphine) (CAS 82239-68-7), molecular formula C31H56O2P2 and molecular weight 522.72 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C31H56O2P2, (((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(dicyclohexylphosphine) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 522.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(dicyclohexylphosphine) 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.
