Tributyl(ethyl)phosphonium Diethyl Phosphate CAS 20445-94-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tributyl(ethyl)phosphonium Diethyl Phosphate.

CATO supplies Tributyl(ethyl)phosphonium Diethyl Phosphate (CAS 20445-94-7), a certified reference material (molecular formula C14H32PC4H10O4P, MW 384.48 g/mol) for analytical method development and quality control.

Structurally, Tributyl(ethyl)phosphonium Diethyl Phosphate (C14H32PC4H10O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -2.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 384.48 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.

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.
