2,4,8,10-Tetra-tert-butyl-6-((2-ethylhexyl)oxy)-12H-dibenzo[d,g][1,3,2]dioxaphosphocine CAS 126050-54-2 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 2,4,8,10-Tetra-tert-butyl-6-((2-ethylhexyl)oxy)-12H-dibenzo[d,g][1,3,2]dioxaphosphocine.

CATO supplies 2,4,8,10-Tetra-tert-butyl-6-((2-ethylhexyl)oxy)-12H-dibenzo[d,g][1,3,2]dioxaphosphocine (CAS 126050-54-2), a certified reference material (molecular formula C37H59O3P, MW 582.84 g/mol) for analytical method development and quality control.

Structurally, 2,4,8,10-Tetra-tert-butyl-6-((2-ethylhexyl)oxy)-12H-dibenzo[d,g][1,3,2]dioxaphosphocine (C37H59O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 582.84 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
