Description

Compared with other compounds in its class, the molecular weight of 327.48 g/mol gives 2-(di-tert-butylphosphine)-1-(2-methoxyphenyl)-1<I>H</I>-pyrrole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(di-tert-butylphosphine)-1-(2-methoxyphenyl)-1<I>H</I>-pyrrole (CAS 1053658-91-5), molecular formula C19H38NOP and molecular weight 327.48 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(di-tert-butylphosphine)-1-(2-methoxyphenyl)-1<I>H</I>-pyrrole (C19H38NOP) is characterized by an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. 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 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.
