Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Di-tert-butyl(2',4',6'-tricyclohexyl-3,6-dimethoxy-[1,1'-biphenyl]-2-yl)phosphane.

Di-tert-butyl(2',4',6'-tricyclohexyl-3,6-dimethoxy-[1,1'-biphenyl]-2-yl)phosphane (CAS 1352726-19-2) is a high-purity analytical reference standard with the molecular formula C40H61O2P and a molecular weight of 604.88 g/mol.

Structurally, Di-tert-butyl(2',4',6'-tricyclohexyl-3,6-dimethoxy-[1,1'-biphenyl]-2-yl)phosphane (C40H61O2P) 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 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 604.88 g/mol, it falls into the 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.
