(R)-(3-hydroxy-2,3-dimethylbutyl)triphenylphosphonium iodide CAS 138079-59-1

Description

The occurrence of (R)-(3-hydroxy-2,3-dimethylbutyl)triphenylphosphonium iodide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(R)-(3-hydroxy-2,3-dimethylbutyl)triphenylphosphonium iodide (CAS 138079-59-1) is a high-purity analytical reference standard with the molecular formula C24H28OPI and a molecular weight of 490.36 g/mol.

The molecular framework of (R)-(3-hydroxy-2,3-dimethylbutyl)triphenylphosphonium iodide (C24H28OPI) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
