Chemical Structure
Description
The occurrence of 1,2-Bis(di-tert-butylphosphinemethyl)benzene is closely related to organophosphorus functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,2-Bis(di-tert-butylphosphinemethyl)benzene (CAS 121954-50-5), a certified reference material (molecular formula C24H50P2, MW 400.60 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Bis(di-tert-butylphosphinemethyl)benzene (C24H50P2) is characterized by organophosphorus functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1,2-Bis(di-tert-butylphosphinemethyl)benzene 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.
