Tributyltetradecylphosphonium chloride CAS 81741-28-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tributyltetradecylphosphonium chloride.

CATO supplies Tributyltetradecylphosphonium chloride (CAS 81741-28-8), a certified reference material (molecular formula C26H56PCl, MW 435.16 g/mol) for analytical method development and quality control.

The molecular framework of Tributyltetradecylphosphonium chloride (C26H56PCl) is characterized by organophosphorus functionality, chlorine substitution. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
