Triphenyl(prop-2-yn-1-yl)stannane CAS 4104-89-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Triphenyl(prop-2-yn-1-yl)stannane.

Triphenyl(prop-2-yn-1-yl)stannane (CAS 4104-89-6), molecular formula C21H18Sn and molecular weight 389.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Triphenyl(prop-2-yn-1-yl)stannane (C21H18Sn) is characterized by a polycyclic aromatic system. 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.
