Compared with other compounds in its class, the molecular weight of 222.40 g/mol gives tert-Butyldimethyl(p-tolyloxy)silane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyldimethyl(p-tolyloxy)silane (CAS 62790-85-6) is a high-purity analytical reference standard with the molecular formula C13H22OSi and a molecular weight of 222.40 g/mol.
Owing to a hydroxyl group, an ether linkage, tert-Butyldimethyl(p-tolyloxy)silane is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.40 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.
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.
