Description

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.

1,1 inverted exclamation marka,1 inverted exclamation marka inverted exclamation marka-Silylidynetrisbenzene; NSC 12565; Triphenylhydrosilane 789-25-3 AB1011399 (CAS 789-25-3) is a high-purity analytical reference standard with the molecular formula C18H34Si and a molecular weight of 278.55 g/mol.

The molecular framework of 1,1 inverted exclamation marka,1 inverted exclamation marka inverted exclamation marka-Silylidynetrisbenzene; NSC 12565; Triphenylhydrosilane 789-25-3 AB1011399 (C18H34Si) is characterized by an organic framework. 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.

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.
