1,4-Bis(2,3,4,5-tetramethyl-1H-phosphol-1-yl)butane CAS 125706-15-2

Description

The occurrence of 1,4-Bis(2,3,4,5-tetramethyl-1H-phosphol-1-yl)butane is closely related to organophosphorus functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,4-Bis(2,3,4,5-tetramethyl-1H-phosphol-1-yl)butane (CAS 125706-15-2), a certified reference material (molecular formula C20H40P2, MW 342.48 g/mol) for analytical method development and quality control.

Structurally, 1,4-Bis(2,3,4,5-tetramethyl-1H-phosphol-1-yl)butane (C20H40P2) contains organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 342.48 g/mol, it falls into the moderately-high-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.

As a certified reference material (CRM), 1,4-Bis(2,3,4,5-tetramethyl-1H-phosphol-1-yl)butane 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.
