Compared with other compounds in its class, the molecular weight of 238.40 g/mol gives (2-((tert-Butyldimethylsilyl)oxy)phenyl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2-((tert-Butyldimethylsilyl)oxy)phenyl)methanol (CAS 96013-79-5), molecular formula C13H22O2Si and molecular weight 238.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (2-((tert-Butyldimethylsilyl)oxy)phenyl)methanol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
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.
