Chemical Structure

Bis(2,4-di-tert-butylphenyl) Hydrogen Phosphate CAS 69284-93-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 474.61 g/mol gives Bis(2,4-di-tert-butylphenyl) Hydrogen Phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bis(2,4-di-tert-butylphenyl) Hydrogen Phosphate (CAS 69284-93-1), a certified reference material (molecular formula C28H43O4P, MW 474.61 g/mol) for analytical method development and quality control.

Structurally, Bis(2,4-di-tert-butylphenyl) Hydrogen Phosphate (C28H43O4P) contains a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 474.61 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.
