2-(Di-t-butylphosphinomethyl)pyridine CAS 494199-72-3

Description

Compared with other compounds in its class, the molecular weight of 237.32 g/mol gives 2-(Di-t-butylphosphinomethyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Di-t-butylphosphinomethyl)pyridine (CAS 494199-72-3), molecular formula C14H24NP and molecular weight 237.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, organophosphorus functionality, 2-(Di-t-butylphosphinomethyl)pyridine is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 237.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
