Chemical Structure
Description
(3-(Tert-butoxy)-2',4',6'-triisopropyl-6-methoxy-[1,1'-biphenyl]-2-yl)dicyclohexylphosphane (CAS 2489243-28-7) is a high-purity analytical reference standard with the molecular formula C38H59O2P and a molecular weight of 578.85 g/mol.
Structurally, (3-(Tert-butoxy)-2',4',6'-triisopropyl-6-methoxy-[1,1'-biphenyl]-2-yl)dicyclohexylphosphane (C38H59O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 578.85 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
