[1,1'-Biphenyl]-4-yltrimethylsilane CAS 1625-88-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [1,1'-Biphenyl]-4-yltrimethylsilane.

[1,1'-Biphenyl]-4-yltrimethylsilane (CAS 1625-88-3) is a high-purity analytical reference standard with the molecular formula C15H18Si and a molecular weight of 226.39 g/mol.

The molecular framework of [1,1'-Biphenyl]-4-yltrimethylsilane (C15H18Si) 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.
