Chemical Structure
Description
As a certified reference material (CRM), 4,4'-(Phenylphosphinediyl)dimorpholine 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.
CATO supplies 4,4'-(Phenylphosphinediyl)dimorpholine (CAS 13337-35-4), a certified reference material (molecular formula C14H21N2O2P, MW 280.30 g/mol) for analytical method development and quality control.
Structurally, 4,4'-(Phenylphosphinediyl)dimorpholine (C14H21N2O2P) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 280.30 g/mol, it falls into the medium-molecular-weight range. 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.
