Chemical Structure
Description
The occurrence of 3-((trimethylsilyl)ethynyl)phenol is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-((trimethylsilyl)ethynyl)phenol (CAS 388061-72-1), molecular formula C11H14OSi and molecular weight 190.31 g/mol, is a CATO reference standard with documented purity and traceability.
3-((trimethylsilyl)ethynyl)phenol (C11H14OSi) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
