Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
((2-Ethylphenyl)ethynyl)trimethylsilane (CAS 492448-53-0), molecular formula C13H18Si and molecular weight 202.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((2-Ethylphenyl)ethynyl)trimethylsilane (C13H18Si) is characterized by an aromatic ring 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.
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.
