Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phosphazene ligand P<SUB>1</SUB>-tert-butyl tris(tetramethylene).
CATO supplies Phosphazene ligand P<SUB>1</SUB>-tert-butyl tris(tetramethylene) (CAS 161118-67-8), a certified reference material (molecular formula C16H33N4P, MW 312.43 g/mol) for analytical method development and quality control.
Phosphazene ligand P<SUB>1</SUB>-tert-butyl tris(tetramethylene) (C16H33N4P) contains a nitrile group, organophosphorus functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Phosphazene ligand P<SUB>1</SUB>-tert-butyl tris(tetramethylene) 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.
