Chemical Structure

Phenethyltriphenylsilane CAS 18849-30-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phenethyltriphenylsilane.

Phenethyltriphenylsilane (CAS 18849-30-4), molecular formula C26H24Si and molecular weight 364.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Phenethyltriphenylsilane (C26H24Si) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
