3-[(tert-Butyldimethylsilyl)oxy]-4-fluorophenol CAS 1881329-11-8

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.

3-[(tert-Butyldimethylsilyl)oxy]-4-fluorophenol (CAS 1881329-11-8), molecular formula C12H19FO2Si and molecular weight 242.36 g/mol, is a CATO reference standard with documented purity and traceability.

3-[(tert-Butyldimethylsilyl)oxy]-4-fluorophenol (C12H19FO2Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
